Abstract

An organic light-emitting display device comprises a substrate; a plurality of sub-pixels arranged in a first horizontal line and a second horizontal line on the substrate; at least one thin film transistor and a first electrode of an organic light-emitting diode connected to the thin film transistor, the at least one thin film transistor and the organic light-emitting diode being disposed in eachof the plurality of sub-pixels; a first bank layer is disposed on the first electrode and exposing the first electrode; and a second bank layer disposed on the first bank layer and exposing the firstbank layer and the first electrode, wherein the second bank layer is consecutively arranged in the first horizontal line and the second horizontal line and including a first bending portion at a boundary between the first horizontal line and the second horizontal line.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to an organic light emitting display device having a double bank structure. Although the present disclosure is applicable to a wide range of applications, it is particularly suitable for providing a uniform thickness of the organic light emitting layer for an organic light emitting display device. Background technique [0002] Various display devices having reduced weight and volume have been developed, which replace conventional display devices using cathode ray tubes. Such display devices include liquid crystal displays (LCDs), liquid crystal display panels (PDPs), field emission displays (FEDs), organic light emitting display devices, and the like. [0003] Organic light emitting display devices include elements that spontaneously emit light and have advantages of high response speed, high emission efficiency, high brightness, and wide viewing angle. In addition, the elemen...
