Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/117609
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress occurrence of a kink phenomenon and improve the image quality of a display device. The display device includes a thin-film transistor provided in a pixel. The thin-film transistor has a semiconductor layer (SC), a first insulating layer (IN1) provided below the semiconductor layer (SC), a second insulating layer (IN2) provided above the semiconductor layer (SC), and a gate electrode (LG, HG, SG) that faces the semiconductor layer (SC) across a gap therebetween. The gate electrode includes a first gate electrode part (LG) that faces the lower surface of the semiconductor layer (SC), a second gate electrode part (HG) that faces the upper surface of the semiconductor layer (SC), and third gate electrode parts (SG) that face side surfaces of the semiconductor layer (SC) and are connected to the first gate electrode part (LG) and the second gate electrode part (HG). A laminated portion in which the first insulating layer (IN1) and the second insulating layer (IN2) are laminated on one another is provided around the semiconductor layer (SC). A part of the laminated portion is located between the side surfaces of the semiconductor layer (SC) and the third gate electrode parts (SG).
