Liquid crystal display device

摘要

A pixel of a liquid crystal display device includes a scan line, a signal line, a TFT, a lower electrode, and an upper electrode arranged thereon with a protection film interposed therebetween, in which the upper electrode includes a plurality of branch electrode parts electrically connected in common, and a gap part between the branch electrode parts. The upper electrode includes a region in which a ratio of a width of the gap part to a width of the branch electrode part that is adjacent to the gap part is different, and includes both of a region in which a light transmittance increases and a region in which the light transmittance decreases with respect to a change in the ratio.

1. A liquid crystal display device comprising:
a pair of substrates; a liquid crystal layer that is sealed between the substrates; and a display area comprising a plurality of pixels arranged therein in matrix on one of the substrates, the pixels being defined by scan lines and signal lines that cross with the scan lines, wherein each of the pixels comprises a switching element, a lower electrode, and an upper electrode that is arranged on the lower electrode with an insulation film interposed therebetween, the upper electrode comprises a plurality of branch electrode parts electrically connected in common, and a gap part between the branch electrode parts, the upper electrode comprises a first region of a pixel wherein a ratio of a width of the gap part to a width of the branch electrode part that is adjacent to the gap part is a first value and a second region of said pixel wherein a ratio of a width of the gap part to a width of the branch electrode part that is adjacent to the gap part is a second value, wherein the second value is different from the first value, and the upper electrode comprises both of a region in which a light transmittance increases, the light transmittance increasing when the ratio of the width of the gap part to the width of the branch electrode part that is adjacent to the gap increases to a first range ratio that is less than a predetermined threshold ratio, and a region in which the light transmittance decreases, the light transmittance decreasing when the ratio of the width of the gap part to the width of the branch electrode part that is adjacent to the gap increases to a second range ratio that is greater than the predetermined threshold ratio.
