Abstract: An in-plane switching mode LCD device includes a shield common electrode having a protrusion protruding from side edges of a drain line, and a pair of light shield films sandwiching therebetween the drain line and having an overlapping portion overlapping the protrusion. The shield common electrode shields the electric field from the drain line, and the light shield films improve the contrast ratio of the LCD device.

Abstract: A LCD device prevents image quality degradation caused by the gap non-uniformity in the display region with a simple measure. A TFT substrate and an opposite substrate are coupled to each other with a sealing member in such a way as to form a gap therebetween. A liquid-crystal layer is formed in the gap. Spacers are arranged in the liquid-crystal layer. The TFT substrate has a display region defined to include the pixels and a non-display region formed outside the display region. The non-display region is located between the display region and the sealing member. The spacers are located in a first part of the liquid-crystal layer corresponding to the display region while no spacer being located in a second part of the liquid-crystal layer corresponding to the non-display region. A depression for receiving extra liquid crystal may be additionally formed in the gap.

Abstract translation: LCD装置以简单的措施防止由显示区域中的间隙不均匀性引起的图像质量劣化。 TFT基板和相对的基板以密封构件彼此连接，以便在它们之间形成间隙。 在间隙中形成液晶层。 间隔物布置在液晶层中。 TFT基板具有限定为包括像素的显示区域和形成在显示区域外部的非显示区域。 非显示区域位于显示区域和密封构件之间。 间隔物位于对应于显示区域的液晶层的第一部分中，而液晶层的与非显示区域相对应的第二部分中没有间隔物。 可以在间隙中另外形成用于接收额外的液晶的凹陷。
