Liquid crystal display device

摘要

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 (30u) in an upper display region and a source line (30d) 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 (32a) 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 (32b) on which the divided position (40) is absent.

主权项

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; 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; and a light blocking film for covering a pixel separation region provided between the pixels adjacent to each other in a horizontal direction, wherein: each of the video wiring lines extends in a vertical direction through the pixel separation region, and is divided for each of the plurality of display regions by providing a divided position in the pixel separation region; and in corresponding one of the pixels adjacent to the divided position, the light blocking film has a planar shape including a convex portion projecting in the horizontal direction in vicinity of the divided position, and in the pixels not adjacent to the divided position as well, the light blocking film has the planar shape so that the respective pixels have a uniform pixel aperture ratio.
