Abstract: According to some aspects, a liquid crystal display panel comprising an electrode is provided. The electrode comprises a plurality of convex branch electrode portions arranged in a plane, the convex branch electrode portions being convex when viewed from a first direction perpendicular to the plane and extending from a central region of the electrode to a periphery of the electrode, and a plurality of concave branch electrode portions, the concave branch electrode portions being concave when viewed from the first direction, extending from the central region to the periphery and adjacent to convex branch electrode portions. According to some aspects, a method of applying a pretilt to molecules in a liquid crystal layer of a liquid crystal display panel by applying a voltage to the liquid crystal layer via first and second electrodes is provided.

Abstract: A liquid crystal display device includes a plurality of arranged pixels. Each of the pixels includes: a first substrate and a second substrate; a first electrode provided on a counter face of the first substrate, the counter face facing the second substrate; a second electrode provided on a counter face of the second substrate, the counter face facing the first substrate; and a liquid crystal layer that contains liquid crystal molecules, and is sandwiched between the first substrate and the second substrate. The liquid crystal molecules are given a pre-tilt. The first electrode includes a base layer 150 that contains a plurality of recesses and protrusions, and transparent conductive material layers 135 and 145. The first transparent conductive material layer 135 connected to a first power supply portion is formed on protrusion top faces 151 of the base layer 150. The second transparent conductive material layer 145 connected to a second power supply portion is formed on recess bottom faces 152 of the base layer 150. The first transparent conductive material layer 135 and the second transparent conductive material layer 145 are separated from each other.

Abstract: A liquid-crystal display apparatus includes a plurality of rectangular pixels 10. Each pixel 10 includes a first electrode 22 and a second electrode. A slit region and a concave and convex portion are formed in the first electrode 22. It further includes a control circuit. The plurality of pixels are constituted of a first pixel group and a second pixel group. First data lines 41 and 42 for applying a voltage on the first electrode 22 are provided closer to the first substrate than the first electrode 22. In each pixel that constitutes the first pixel group, a second data line extension 42A extending from a second data line 42 is provided adjacent to a first data line 41. In each pixel that constitutes the second pixel group, a first data line extension 41A extending from the first data line 41 is provided adjacent to the second data line 42.
