Document Type and Number:
WIPO Patent Application WO/2022/153146
Kind Code:
A1
Abstract:
The present invention provides a novel display device. The display device has a first layer, a second layer, and a third layer. Each of the first layer, the second layer, and the third layer is provided in a different layer. The first layer has a driving circuit and a functional circuit. The second layer has a pixel circuit. The third layer has a display element. The pixel circuit has a function for controlling the light emission of the display element. The driving circuit has a function for controlling the pixel circuit. The functional circuit has a function for controlling the driving circuit. The first layer has a first transistor that has a semiconductor layer having silicon in a channel forming region. The second layer has a second transistor that has a semiconductor layer having a metal oxide in a channel forming region.
