ORGANIC ELECTROLUMINESCENCE DISPLAY PANEL AND METHOD OF MANUFACTURING SAME

摘要

A organic EL display panel includes an inter-layer insulation film, a pixel electrode, auxiliary wiring, a partition layer, an organic light-emitting layer, and a common electrode. The inter-layer insulation film has at least one paired concave portion and non-concave portion disposed in a region over the auxiliary wiring, a top face of the concave portion being concave with respect to a top face of the non-concave portion, and the auxiliary wiring includes a part over the concave portion and a part over the non-concave portion, a top face of the part over the concave portion being concave with respect to a top face of the part over the non-concave portion.

主权项

1. An organic electroluminescence display panel, comprising:
a substrate; a thin film transistor disposed over the substrate; an inter-layer insulation film disposed over the thin film transistor; a pixel electrode disposed over the inter-layer insulation film; auxiliary wiring disposed over the inter-layer insulation film with separation from the pixel electrode; a partition layer disposed over the inter-layer insulation film and having openings respectively arranged over the pixel electrode and over the auxiliary wiring; an organic light-emitting layer disposed in the openings over the pixel electrode; and a common electrode facing the pixel electrode through the openings over the pixel electrode and electrically connected to the pixel electrode via the organic light-emitting layer, and also facing the auxiliary wiring through the openings over the auxiliary wiring and electrically connected to the auxiliary wiring, wherein the inter-layer insulation film has at least one paired concave portion and non-concave portion disposed in an area over which the auxiliary wiring is disposed, a top face of the concave portion being concave with respect to a top face of the non-concave portion, and the auxiliary wiring includes a part over the concave portion and a part over the non-concave portion, a top face of the part over the concave portion being concave with respect to a top face of the part over the non-concave portion.
