Document Type and Number:
WIPO Patent Application WO/2023/100015
Kind Code:
A1
Abstract:
Provided is a display device having high luminance and a long service life. A display apparatus having a first layer and a second layer that is positioned above the first layer. The first layer has a substrate and a plurality of driving circuit regions, and the second layer has a plurality of display regions. In addition, the substrate is a glass substrate. Each of the plurality of driving circuit regions has a driving circuit, the driving circuit having a transistor that includes silicon in a channel-forming region. Each of the plurality of display regions has a pixel, the pixel having a light-emitting diode and a transistor that includes a metal oxide in a channel-forming region. In particular, the light-emitting diode is preferably a micro light-emitting diode. The driving circuit included in one of the plurality of driving circuit regions has a function for driving the display pixel included in one of the plurality of display regions.
