| 20090213053 | Liquid Crystal Display Device - A liquid crystal display device includes a plurality of pixels each connected to a signal line via a switching element. Each pixel includes first and second sub-pixels having voltage vs. luminance characteristics different from each other with respect to a signal voltage supplied from the signal line. A threshold signal voltage of the first sub-pixel is lower than that of the second sub-pixel. The pixels form color display pixels which are red, green pixel and blue pixels. Where the area ratio of the first sub-pixel in each of the red, green and blue pixels is SR1, SG1 and SB1, and the ratio of the lighting-up time period of the first sub-pixel of each of the red, green and blue pixels in one vertical scanning period is TR1, TG1 and TB1, the relationship of (SR1×TR1)>(SG1×TG1)>(SB1×TB1) holds. | 08-27-2009 |
| 20090267880 | LIQUID CRYSTAL DISPLAY DEVICE - A pixel has a first liquid crystal domain. In the first liquid crystal domain, first and second pretilt directions of liquid crystal molecules, defined by first and second alignment films, respectively, intersect with each other at substantially right angles. Also, in the first liquid crystal domain, when a signal voltage is applied to the liquid crystal layer to display the highest gray scale, liquid crystal molecules, located around the center of a plane of the liquid crystal layer and around the middle of the thickness of the liquid crystal layer, are tilted in a first direction that substantially equally divides the first and second pretilt directions into two. A driver applies a signal voltage to the liquid crystal layer of the pixel every vertical scanning period. At least while display gray scales are changing from the lowest gray scale into the highest one, the driver applies a voltage that is at least 0.96 times as high as the threshold voltage Vth of the liquid crystal layer in a vertical scanning period just before the signal voltage is applied to display the highest gray scale. | 10-29-2009 |
| 20090284703 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device includes: a vertical alignment liquid crystal layer; first and second substrates facing each other with the liquid crystal layer interposed; first and second electrodes arranged on the first and second substrates to face the liquid crystal layer; and at least one alignment film in contact with the liquid crystal layer. A pixel region includes a first liquid crystal domain in which liquid crystal molecules are tilted in a first direction around the center of a plane, and approximately at the middle of the thickness, of the liquid crystal layer responsive to a voltage applied. The first liquid crystal domain is close to at least a part of an edge of the first electrode. The part includes a first edge portion in which an azimuthal direction, perpendicular to the part and pointing toward the inside of the first electrode, defines an angle greater than 90 degrees to the first direction. The first or second substrate has an opaque member including a first opaque portion for selectively shielding at least a part of the first edge portion from incoming light. | 11-19-2009 |
