Abstract: In an IPS mode liquid crystal display device, measures are taken against dark unevenness at the corner portion of a screen. The problem can be solved by a liquid crystal display device in which a comb tooth pixel electrode is formed on a common electrode formed in a flat surface through an interlayer insulating film; a TFT substrate is formed with a dummy pixel region and a display region surrounding the display region; a pixel on the display region is formed with a comb tooth display region pixel electrode bent in a projection in the first direction; and a pixel on the dummy pixel region is formed with a comb tooth dummy pixel region pixel electrode bent in a projection in a direction opposite to the first direction at an angle of 180 degrees.

Abstract: Reduction in the reliability of a seal portion is prevented. The reduction is caused by a light shielding portion formed on the seal portion of a TFT substrate to hamper curing an ultraviolet curable sealing material. A sealing material has a two-layer structure of an ultraviolet curable sealing material that is an inner sealing material and a thermosetting and ultraviolet curable sealing material or a thermosetting sealing material that is an outer sealing material. A light shielding portion is formed on a TFT substrate under the outer sealing material, and is not formed on the TFT substrate under the inner sealing material. When ultraviolet rays are applied from the TFT substrate side, the inner sealing material is cured in a short time. The outer sealing material is then cured by heating. Thus, the overall seal portion can be sufficiently cured, and a highly reliable seal portion can be formed.

Abstract: A thin-film transistor includes a gate electrode made of metal, a light transmissive gate insulating film that covers the gate electrode, a semiconductor film that overlaps with the gate electrode through the gate insulating film, and a source electrode and a drain electrode, made of metal, and spaced from each other. The gate electrode and the semiconductor film have respective through-holes communicated with each other so that the gate insulating film enters an inside of the through-holes. The gate insulating film has an area of the inside of the through-holes of the gate electrode and the semiconductor film. The source electrode and the drain electrode pass through the inside of the through-holes of the gate electrode and the semiconductor film so as to overlap with a part of the area of the inside of the through-hole of the gate insulating film and avoid a remaining portion thereof.
