DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/185389
Kind Code:
A1
Abstract:
This display device comprises: a plurality of pixel circuits arranged in a matrix and each including (i) a holding capacitor (C1) which is formed from a second electrode (62) that is an upper electrode, a first electrode (60) that is a lower electrode, and a second passivation layer (20) and an upper gate insulating film (116) that are sandwiched between the second electrode (62) and the first electrode (69), and (ii) a drive transistor, the gate electrode of which is connected to the holding capacitor (C1); and first connection wiring (66) electrically connecting the respective first electrodes (60) of two pixel circuits adjacent in the row direction. Each second electrode (62) is formed in an island shape. In a planar view, all outer peripheral edges (62e) of each second electrode (62) overlap a first electrode (60).
