Abstract
The present disclosure relates to an organic light-emitting display device capable of preventing threshold voltage variation in a thin film transistor. In the organic light-emitting display device according to the present disclosure, an upper light-shielding layer overlying a pixel driving circuit which drives a light-emitting element is disposed on the same plane as an anode electrode and a bank is disposed to cover the sides of the upper light-shielding layer, and thus light input to the sides and the upper surface of an active layer can be blocked.
Claims18
An organic light-emitting display device, comprising:
- light-emitting elements disposed on a substrate, each light-emitting element including an anode electrode;
- pixel driving circuits, each pixel driving circuit connected to a corresponding light-emitting element;
- an upper light-shielding layer overlying the pixel driving circuits, the upper light-shielding layer including sides;
- and
- a bank layer providing emission areas in which the light-emitting elements are arranged, and the bank layer disposed to cover the sides of the upper light-shielding layer.
An organic light-emitting display device comprising:
- a substrate comprising an emission area and a driving circuit area;
- at least one light emitting element disposed at the emission area;
- at least one transistor element disposed at the driving circuit area, the at least one transistor element being connected with the least one light emitting element;
- an upper light-shielding layer disposed over the at least one transistor element to block the light incident to a side surface and/or upper surface of an active layer of the at least one transistor element.
