Problems solved by technology

[0016] However, in the OLED device according to the related art, the anti-reflection layer 90 generally provided in a film type is formed in both the TET region and the display region, which reduces the light transmittance of the display region and the brightness of the OLED device.
That is, in the case where light emitted from the light emitting layer 70 passes through the substrate 10 and then passes through the antireflection layer 90, a considerable amount of light is absorbed in the antireflection layer 90, thereby causing light loss.

Abstract

Disclosed in the present invention is an organic light-emitting display (OLED) device and a manufacturing method thereof. The OLED device may include: a first pixel and a second pixel on a substrate, and each of the first pixel and the second pixel includes a TFT region and A display area, the display area of ​​each of the first pixel and the second pixel includes a first electrode, a light emitting layer, and a second electrode; a color filter layer in the display area of ​​the second pixel; and, the first pixel and the second pixel In the second pixel but substantially excluding the anti-reflection layer of the display area of ​​the second pixel.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2013-0136465 filed on November 11, 2013, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention relates to an organic light emitting display (OLED) device and a manufacturing method thereof, and more particularly to an OLED device provided with an anti-reflection layer and a manufacturing method thereof. Background technique [0003] An organic light emitting display (OLED) device includes a light emitting layer disposed between a negative electrode for injecting electrons and a positive electrode for injecting holes. When electrons generated in the negative electrode and holes generated in the positive electrode are injected into the inside of the light emitting layer, excitons are generated by recombination of the electrons and holes. Then, when the excitons drop from the excited state to a lower energy state, the OLED device emits ...
