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 translation: 防止了密封部的可靠性降低。 还原是由形成在TFT基板的密封部分上的遮光部分引起的，从而妨碍紫外线固化的密封材料的固化。 密封材料具有作为内部密封材料和热固性和紫外线固化型密封材料或作为外部密封材料的热固性密封材料的紫外线固化型密封材料的两层结构。 在外部密封材料下面的TFT基板上形成遮光部，不在内侧密封材料下的TFT基板上形成遮光部。 当从TFT基板侧施加紫外线时，内密封材料在短时间内固化。 然后通过加热固化外部密封材料。 因此，能够充分固化整体密封部，能够形成高可靠性的密封部。
