20100079716 | WIRING FIGURE PATTERN OF DISPLAY PANEL - In a wiring figure pattern of a display panel, each wiring is separated into bands of optimal widths by slits of a constant width as a wiring figure pattern so that minimum light irradiation for curing a photocuring sealing material can be carried out without increasing the electric resistance of the wiring. The optimal width means a resistance such that light coming from both sides of the band cures the sealing material on the upper surface of the band without influencing the driving and display of liquid crystal. At a point where the width of wiring becomes two times or more of the optical width between the start point and end point of intersection of the wiring and the sealing material region, the wiring is divided by the slit. A first branch forms the band of the optimal width extending from the branch point to the end point, whereas the second branch extends to the end point and is spaced apart from the first branch by the width of the slit. At a point where the width becomes two times or more of the optimal width, the wiring is divided. Subsequently, branching is repeated until the end point is reached. A continuous triangle is formed in the slit at each branch, thus adjusting the width of the bands to have the optimal width. | 04-01-2010 |
