LUMINESCENT DISPLAY DEVICES

Abstract

The invention relates to a luminescence display device whose display quality is enhanced by reducing the reflection of external light. The invention proposes a luminescence display device comprising: a phototransmitting layer on a substrate, which includes a first metal layer and a second metal layer on top of the first metal layer; a first buffer layer covering at least part of the phototransmitting layer on the substrate; a second buffer layer on top of the first buffer layer; a gate isolation layer on top of the second buffer layer; a gate on the gate isolation layer, not overlapping the phototransmitting layer, which includes a third metal layer and a fourth metal layer on top of the third metal layer; a passivation layer covering at least part of the gate; a leveling layer between the passivation layers; and an emitting element comprising a first electrode, an emitting layer, and a second electrode arranged sequentially on the leveling layer.
