Liquid crystal display device
View Patent ↗Provided is a liquid crystal display device in which a source line is divided in a screen and the screen is driven in a horizontally divided state. A divided position ( 40 ) between a source line ( 30 u ) in an upper display region and a source line ( 30 d ) in a lower display region is arranged at an intersecting part between a source line ( 30 ) and a gate line ( 32 ). A part of the source line ( 30 ), which overlaps with a gate line ( 32 a ) on which the divided position 40 is present, has a planar shape additionally including an expanded part ( 46 ) (protruding portion) having the same area as a removed part of the source line ( 30 ) at the divided position ( 40 ), as compared to a part of the source line ( 30 ), which overlaps with a gate line ( 32 b ) on which the divided position ( 40 ) is absent.
1. A liquid crystal display device, comprising:
a pair of substrates arranged opposed to each other while sandwiching liquid crystal therebetween;
scanning wiring lines extended on one of the pair of substrates along rows of pixels arranged in matrix, respectively, for applying a selection voltage which enables writing of a pixel signal to the pixel rows; and
video wiring lines extended on the one of the pair of substrates along columns of the pixels, respectively, for supplying the pixel signal to corresponding one of the pixel rows, to which the selection signal is applied,
the liquid crystal display device employing a division driving method of performing vertical scanning for each of a plurality of display regions obtained by horizontally dividing a screen, wherein:
each of the video wiring lines is divided for each of the plurality of display regions;
the each of the video wiring lines has a divided position arranged at a part intersecting with corresponding one of the scanning wiring lines; and
the each of the video wiring lines has a part which overlaps with the corresponding one of the scanning wiring lines, on which the divided position is present, the part having a planar shape additionally including an expanded part having the same area as a removed part of the each of the video wiring lines at the divided position, as compared to a part of the each of the video wiring lines, which overlaps with corresponding one of the scanning wiring lines on which the divided position is absent.
