Abstract

A display device comprises a flexible base substrate; a first active pattern and a second active pattern disposed on the base substrate; an inorganic insulating layer disposed on the first and second active patterns and defining an opening area; a first organic insulating pattern disposed inside the opening area; a bridge electrode disposed on the first organic insulating pattern; a second insulating layer disposed on the bridge electrode; a fourth organic insulating layer disposed on the second organic insulating layer; a first pixel electrode, electrically connected to the first active pattern, and a second pixel electrode, electrically connected to the second active pattern, which are disposed on the fourth organic insulating layer; and a third organic insulating pattern disposed between the second organic insulating layer and fourth organic insulating layer, overlapping the second pixel electrode, and not overlapping the first pixel electrode.

Description

technical field [0001] The present invention relates to a display device. More specifically, the present invention relates to flexible display devices having an improved display quality. Background technique [0002] Recently, with the development of technology, display products having smaller size, lighter weight, and better performance are being produced. A conventional cathode ray tube (CRT) television has been widely used as a display device having many advantages in performance and price. However, display devices such as plasma display devices, liquid crystal display devices, organic light-emitting display devices, etc., which overcome the disadvantages of CRTs in miniaturization or portability and have advantages such as miniaturization, light-weight characteristics, and low power consumption, are attracting attention . [0003] An organic light emitting display (OLED) element may be configured such that holes supplied from an anode and electrons supplied from a cat...
