Title: Display device
Inventor: YAMAZAKI SHUNPEI
IPC: G02F1/1368
Filed: 2019-06-27
Abstract: To improve reliability of a drive circuit.SOLUTION: A second high-resistance drain region 432 (or first high-resistance drain region 431) is formed in an oxide semiconductor layer which overlaps a drain electrode layer 405b (and source electrode layer 405a). By forming the second high-resistance drain region 432, a structure can be achieved where conductivity can be gradually varied from the drain electrode layer to the second high-resistance drain region 432 and a channel formation region. Accordingly, a structure can be achieved where locally high electric field is prevented from being applied because the high-resistance drain region serves as a buffer even when high electric field is applied between the gate electrode layer 401 and the drain electrode layer 405b when the drain electrode layer 405b is connected to wiring for supplying high power supply potential VDD to be operated thereby to achieve improved breakdown voltage of a transistor.SELECTED DRAWING: Figure 2
