Problems solved by technology

For example, in a structure in which a sealing substrate is provided on top of an organic light-emitting layer, when the sealing substrate is pressurized to the pixel side, if the thickness of the pixel defining film is too small, dark spots may be induced due to direct pressure on the pixels.
In addition, if the thickness of the pixel defining film is thin, undesirable capacitance will be generated between the wiring provided in the lower part of the pixel defining film and the plurality of electrodes provided in the upper part.

Abstract

An organic light emitting diode (OLED) display is provided. The OLED display includes: a substrate; a first electrode on the substrate; a first pixel defining layer exposing at least a portion of the first electrode; a medium layer on the first pixel defining layer and the first electrode, the medium layer including a first region and a second region; a second pixel defining layer overlapping the first pixel defining layer with the first region therebetween; a light emission layer overlapping the first electrode with the first region therebetween; and a second electrode covering the second pixel defining layer and the light emission layer.

Description

technical field [0001] The present invention relates to an organic light emitting display device and a manufacturing method thereof, and more particularly, to an organic light emitting display device including a pixel defining film and an organic light emitting layer and a manufacturing method thereof. Background technique [0002] An organic light emitting display device (Organic Light Emitting Diode Display; OLED display) is a self-luminous display device. An organic light emitting display device includes an organic light emitting layer disposed between two electrodes. When the two electrodes inject electrons and holes into the organic light-emitting layer, excitons are formed as the electrons and holes combine, and light is generated when the excitons change from an excited state to a ground state. . [0003] The organic light emitting layer is arranged on each pixel of the organic light emitting device. The organic light emitting layers within each pixel are spatially...
