WIPO Patent Application WO/2019/239468

A1

The present invention has: a reflective liquid crystal display pixel (30) that is formed in a first region (R) on a TFT substrate (20) and above an insulating layer (25) having at least the upper surface thereof comprising an inorganic insulating film (25b), and that has a reflective electrode (31), a liquid crystal layer (32), and a counter electrode (33); and a light-emitting element (40) that is formed in a second region (T) above the insulating layer (25) of the TFT substrate (20), and that has a first electrode (41), a light-emitting layer (43), and a second electrode (44). In addition, the light-emitting element has a covering layer (45) that covers the entirety of each light-emitting region of each pixel, and a side edge of the covering layer is bonded to the inorganic insulating film (25b) of the insulating layer whereby the upper surface of the insulating layer (25), metal films (41a, 41, 18c2) that block contact holes of the insulating layer, and inorganic films of the covering layer (45) are bonded to each other, so that the light-emitting layer and the second electrode are completely sealed.
