A liquid crystal display includes a first insulation substrate and a second insulation substrate on which a first pixel, a second pixel, and a third pixel are located. In the first pixel, no columnar spacer equivalent to a first columnar spacer or the second columnar spacer is provided. In the second pixel, a second interlayer insulation film has no contact hole below the first columnar spacer. In the third pixel, no common wire is provided and a third interlayer insulation film has no contact hole below the second columnar spacer.

Liquid crystal display and method for manufacturing the same

An array substrate includes: a gate wiring; a source wiring, which is formed to intersect the gate wiring; a passivation film, which covers the source wiring; and a pixel electrode that is formed on the passivation film. The array substrate has a display area and a dummy pixel area. In the display area, a switching element in the vicinity of the intersection of the gate wiring and the source wiring is provided. In the display area, the pixel electrode and the source wiring do not have an overlapping area in a top view. The dummy pixel area is located outside the display area, and in the dummy pixel area, a dummy pixel electrode and two source wirings, which are adjacent to the dummy pixel electrode have an overlapping area in a top view.

According to an aspect of the present invention, there is provided a liquid crystal display that includes a gate electrode and line formed on a transparent insulating substrate, a gate insulating film covering the gate electrode and line, a semiconductor layer formed on the gate insulating film, a source electrode, a source line, and a drain electrode formed on the semiconductor layer, and a pixel electrode connected to the drain electrode. The semiconductor layer is integrally formed of three portions which are a crossover portion of the source line and the drain line, a TFT portion, and a connecting portion connecting the crossover portion to the TFT portion. A part of the crossover portion on the connecting portion side and the whole connecting portion are covered by the source electrode and the source line.
