THIN-FILM TRANSISTOR DEVICE AND DISPLAY DEVICE USING SAME

摘要

A display device including: a lead wiring layer pattern 207, made from metal, that extends outside a region 10A on a substrate in which a light-emitter is present; a passivation layer 216; a contact hole 216a in the passivation layer 216 outside the region 10A in a position over the lead wiring layer pattern 207 in plan view; a connecting wiring layer pattern 237 that is continuous across the passivation layer 216, an inner circumference of the contact hole 216a, and the lead wiring layer pattern 207 in the contact hole 216a; a sealing layer 217 covering a portion of the connecting wiring layer pattern 237 in the contact hole 216a; and an upper sealing layer pattern 219 covering the sealing layer pattern 217 that is above the connecting wiring layer pattern 237.

主权项

1. A display device comprising:
a substrate; a light-emitter disposed on the substrate; a transistor that drives the light-emitter; a lead wiring layer pattern, made from metal, that extends from a source, drain, or gate of the transistor to an outer region outside a region in which the light-emitter is present; a passivation layer in which a contact hole is opened, the passivation layer being disposed covering the lead wiring layer pattern, the contact hole, in plan view, being superimposed over the lead wiring layer pattern in the outer region; a connecting wiring layer pattern that is continuous across the passivation layer, an inner circumference of the contact hole, and the lead wiring layer pattern in the contact hole; a sealing layer pattern disposed on the connecting wiring layer pattern, covering a portion of the connecting wiring layer pattern in the contact hole; and an upper sealing layer pattern disposed above the connecting wiring layer pattern, covering the sealing layer pattern.
