| 20100245699 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device and a manufacturing method thereof which can suppress chipping of an alignment film or the like are provided. A liquid crystal display device and a manufacturing method thereof which can obviate the complication of manufacturing steps and the increase of a manufacturing cost are also provided. A liquid crystal display device includes: a TFT substrate; a counter substrate; and liquid crystal sandwiched between the TFT substrate and the counter substrate. A plurality of color filters are arranged on the counter substrate, and spacers are formed by stacking the plurality of color filters and by covering a surface of stacked color filters with an overcoat layer. Pedestals are formed on the TFT substrate in a state where the pedestal faces the spacer in an opposed manner. The pedestal is formed by stacking at least a semiconductor layer and a metal layer formed which are simultaneously with a thin film transistor on the TFT substrate. A width of a pedestal portion constituted of the semiconductor layer is substantially equal to a width of the spacer. | 09-30-2010 |
| 20100191802 | Presence information management system and presence information management server - When starting subscribe for acquiring presence information, there is no need of acquiring an identifier of the presentity or an identifier of the group, which have been conventionally indispensable. There is provided a state information management system including a management server for managing state information on a plurality of terminals. Instead of specifying a presentity, a condition of the presentity, such as a value of presence, is specified for subscribing. For example, when subscribe is established by specifying the identical current position as a condition, subscribe for the user matched with the condition is automatically started and the presence can be acquired. When the presence of a partner or user himself/herself is changed to a different value, the presentity is automatically changed. | 07-29-2010 |
