Abstract: A display device is described that has reduced resistance in one or more of the gate, common, data electrical lines that control the operation of the pixels of the display device. Reduced resistance is achieved by forming additional metal and/or metal-alloy layers on the gate, common, and/or data lines in such a manner so that the cross-sectional area of those lines is increased. As a consequence, each such line is formed so as to be thicker than could otherwise be achieving without causing defects in the rubbing process of an alignment layer. Additionally, no widening of these lines is needed, thus preserving the aspect ratio of the device. The gate insulating and semiconducting layers that in part make up the thin film transistors that help control the operation of the pixels of the device may also be designed to take into account the increased thickness of the lines.
Abstract translation: 描述了在控制显示装置的像素的操作的一个或多个栅极，公共数据电线中降低电阻的显示装置。 通过在栅极，公共和/或数据线上形成额外的金属和/或金属合金层，使得这些线的横截面面积增加，可实现降低电阻。 结果，每个这样的线形成为比否则可以实现的厚，而不引起对准层的摩擦过程中的缺陷。 另外，不需要扩大这些线，因此保持了装置的纵横比。 部分地构成薄膜晶体管的栅极绝缘层和半导体层有助于控制器件的像素的操作也可以被设计成考虑到线的增加的厚度。

Abstract: Discussed is a display device in which a photo transistor that senses light from a light-emitting element is disposed in a separate wiring substrate from a panel unit in which the light-emitting element is disposed. Thus, the photo transistor is used as a component of a compensation unit that compensates for a difference between luminance of pixels based on a sensing result of the light from the light-emitting element.
