Abstract

The present invention provides a display device, comprising: a substrate; a first metal conductive layer located on the substrate; a semiconductor layer located on the first metal conductive layer and having a top surface; and a second metal conductive layer, It is located on the top surface and cooperates with the first metal conductive layer and the semiconductor layer to form a thin film transistor structure, and has a first part and a second part, the first part extends toward the second part and forms a channel region with the semiconductor layer; wherein, The direction from the first part to the second part is a first extension direction, the area where the first part overlaps with the first metal conductive layer in the first extension direction has a maximum length, and the first part overlaps with the semiconductor layer in a direction perpendicular to the first extension direction The region of has a maximum width, a maximum length greater than the maximum width and less than or equal to twice the maximum width.

Description

technical field [0001] The present invention relates to a display device, especially a display device in which the source or drain has a specific size to ensure the switching characteristics and display quality of the thin film transistor structure. Background technique [0002] With the continuous advancement of display technology, all display devices are developing toward small size, thin thickness, and light weight. Therefore, the current mainstream display devices on the market have developed from the previous cathode ray tubes to thin displays, such as liquid crystal display devices or Organic light-emitting diode display devices, etc. Among them, liquid crystal display devices or organic light-emitting diode display devices can be applied in quite a few fields. Most of the display devices such as mobile phones, notebook computers, video cameras, cameras, music players, mobile navigation devices, and televisions used in daily life use these display panels. [0003] Al...
