Abstract

A semiconductor device includes a p-type TFT having a first semiconductor layer, and an n-type TFT having a second semiconductor layer. A tilted portion, which is widened toward the insulating substrate side, is formed in at least a part of an outer edge portion of the first semiconductor layer. A tilt angle of a surface of the tilted portion to a surface of an insulating substrate, which is an angle formed inside the first semiconductor layer, is smaller than an angle of a side surface of an outer edge portion of the second semiconductor layer to the surface of the insulating substrate, which is an angle formed inside the second semiconductor layer.

Description

technical field

[0001] The present invention relates to a semiconductor device and its manufacturing method. Background technique

[0002] In recent years, so-called thin display devices such as liquid crystal display devices have been widely used in mobile devices such as mobile phones and various devices such as television monitors. Here, an active matrix type liquid crystal display device is described as an example. The liquid crystal display device includes an active matrix substrate, a counter substrate provided to face the active matrix substrate, and a liquid crystal layer sealed between these substrates.

[0003] A common electrode, a color filter, and the like are formed in the counter substrate. On the other hand, the active matrix substrate has a plurality of pixels arranged in a matrix, and a thin film transistor (hereinafter abbreviated as TFT) as a switching element is formed in each pixel. Then, drive control is performed on each TFT, and a drive voltage is ...
