Abstract: A LCD device having a large pixel holding capacitance includes opposedly facing first and second substrates, and liquid crystal between them. The first substrate includes a video signal line, a pixel electrode, a thin film transistor having a first electrode connected to the video signal line and a second electrode connected to the pixel electrode, a first silicon nitride film formed above the second electrode, an organic insulation film above the first silicon nitride film, a capacitance electrode above the organic insulation film, and a second silicon nitride film above the capacitance electrode and below the pixel electrode. A contact hole etched in both the first and second silicon nitride films connects the second electrode and the pixel electrode to each other. A holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.

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。
