| 20090134786 | Organic EL display device and manufacturing method thereof - A manufacturing method of an organic EL display device which can suppress a manufacturing cost while effectively preventing organic EL layers from being influenced by moisture is provided. An organic EL element is covered with a resin sheet. The resin sheet is adhered to a sealing substrate and an element substrate on which organic EL elements are formed by lamination. Laser beams are radiated to a terminal portion formed on the element substrate so as to generate impact waves in the terminal portion by laser beams thus removing the resin sheet from the terminal portion. Thereafter, edge portions of the sealing substrate and edge portions of the resin sheet are removed along a line a. Due to such steps, it is possible to manufacture highly reliable organic EL display devices at a low cost. | 05-28-2009 |
| 20090200924 | Oganic EL display device and manufacturing method thereof - A sealing method of an organic EL display device which can effectively prevent the organic EL display device from being influenced by moisture and can suppress the manufacturing cost of the organic EL display device is provided. An organic EL element is covered with a resin sheet. The resin sheet is adhered to a sealing substrate and an element substrate on which organic EL elements are formed by lamination. At a peripheral portion of the organic EL display device, between the element substrate and the sealing substrate, an organic seal is filled to a side portion of the resin sheet using an under-filling method, and the organic seal is cured by radiating ultraviolet rays. Due to such constitution, it is possible to realize the highly reliable sealing of the organic EL display devices at a low cost. | 08-13-2009 |
| 20090243474 | Organic EL display device - A sealing substrate is arranged to oppositely face an element substrate on which organic EL layers are formed in a matrix array with a sealing material sandwiched therebetween. A gel-state desiccant is filled in an inner space surrounded by the element substrate, the sealing substrate and the sealing material. Since the gel-state desiccant is in a gel state, the gel-state desiccant is flexibly filled in the inner space of the organic EL display device thus completely eliminating a gap. Since the inner space is filled with the gel-state desiccant, moisture hardly intrudes into the inner space from the outside and, at the same time, a mechanical strength of the organic EL display device is also enhanced. | 10-01-2009 |
| 20100035505 | MANUFACTURING METHOD OF ORGANIC EL DISPLAY DEVICE - A mother element substrate and a mother seal substrate are adhered with each other via an adhesive sheet. An adhesive sheet cut portion of the adhesive sheet corresponding to a terminal portion is formed at a time when the adhesive sheet is applied to the mother seal substrate, thus requiring no processing of the terminal portion afterward. Since the adhesive sheet cut portion extends to reach an edge of the adhesive sheet to prevent deformation of the adhesive sheet around the terminal portion after adhering the mother element substrate and the mother seal substrate with each other under the negative pressure so as to be returned to the atmosphere, thus realizing the solid seal type organic EL display device with high reliability. | 02-11-2010 |
| 20100060158 | ORGANIC EL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - An organic EL display panel which does not impair a sealing effect and ensures a smooth edge portion when individual organic EL display panels are separated from a mother panel on which a plurality of organic EL display panels are formed is provided. A mother panel is formed by adhering a mother element substrate and a mother sealing substrate by way of an adhesive material sheet. In separating the mother panel into individual organic EL display panels, laser beams are radiated to the mother panel along separation lines so as to lower an adhesive strength of the adhesive material sheet at such portions. Thereafter, scribing is applied to the mother panel along the separation lines. Due to such a constitution, it is possible to realize an organic EL display panel without lowering a sealing effect and ensuring smooth appearance. | 03-11-2010 |
| 20100102302 | ORGANIC ELECTROLUMINESCENCE DEVICE - An organic electroluminescence device which can prevent the deterioration thereof attributed to moisture by preventing a desiccant from influencing organic electroluminescence elements is provided.
