Abstract: There is provided a high-definition liquid crystal display device that can prevent flicker due to a reduction in the pixel potential in a low-frequency drive of about 10 Hz to reduce power consumption. The pixel has a TFT formed of Poly-Si as a switching element. In the pixel, a capacitance insulating film is formed on a planar first electrode on which a comb-shaped second electrode is fanned. When the film thickness of the insulating film is d and the dielectric constant at 10 Hz frequency is ε, it is given that εd≧5×10−6 m at 10 Hz frequency. The capacitance insulating film does not have a hysteresis characteristic. The refractive index of the capacitance insulating film with respect to a light of a wavelength of 632.8 nm is 1.7 to 2.0.

Abstract: The present invention prevents the shaving of an alignment film caused by a columnar spacer in a liquid crystal display device of an IPS method using photo-alignment. A plinth higher than a pixel electrode is formed at a part where a columnar spacer formed over a counter substrate touches a TFT substrate. When an alignment film of a double-layered structure is applied over the pixel electrode and the plinth, the thickness of the alignment film over the plinth reduces by a leveling effect. When photo-alignment is applied in the state, a photodegraded upper alignment film over the plinth disappears and a lower alignment film having a high mechanical strength remains. As a result, it is possible to prevent the shaving of the alignment film.
Abstract translation: 本发明防止了使用光取向的IPS方法的液晶显示装置中的柱状间隔物引起的取向膜的刮削。 在对置基板上形成的柱状间隔件与TFT基板接触的部分，形成比像素电极高的底座。 当在像素电极和底座上施加双层结构的取向膜时，底座上的取向膜的厚度减小了平整效应。 当在该状态下进行光对准时，在底座上的光降解的上取向膜消失，并且残留有机械强度较高的下取向膜。 结果，可以防止取向膜的刮削。

Abstract: A reliability of seal portion of a liquid crystal display device can be improved by the following structure. A liquid crystal display device includes: a TFT substrate which includes a display region and a terminal part, and has an inorganic insulating film formed on an organic passivation film and an alignment film formed over the inorganic insulating film; a counter substrate, the TFT substrate and the counter substrate bonded together by a sealing material formed at a seal part surrounding the display region; and a liquid crystal sealed inside. At the seal part, a transparent conductive oxide film is formed between the inorganic insulating film and the alignment film. The transparent conductive oxide film exists inside an edge of the TFT substrate and hence, the edge of the TFT substrate is free of the transparent conductive oxide film.
