Document Type and Number:
WIPO Patent Application WO/2022/172411
Kind Code:
A1
Abstract:
A display device (1) comprises: a substrate layer (10) in which a second resin substrate layer (16) is provided on an inorganic substrate layer (14); a light-emitting element layer (60) provided above the second resin substrate layer; and a sealing film (80) provided on the light-emitting element layer. A through-hole (H) is formed in a non-display region (N) of the display device. In the non-display region, a recessed portion (100) is formed around the through-hole of the second resin substrate layer. An end surface facing the inside of the recessed portion of the resin substrate layer constitutes an inclined end surface (102). An inorganic sealing layer extends into the recessed portion so as to cover the inclined end surface, and abuts on the inorganic substrate layer in the recessed portion. An end surface on the through-hole side of the inorganic sealing layer is located at a position away from the peripheral edge of the through-hole.
