Problems solved by technology

However, there is a problem that the thickness of the coated polarizing film is still large, and if the thickness is reduced, the function and display quality of the polarizing film deteriorate
Therefore, it is difficult to realize a polarizing film for a pressure-foldable display device

Abstract

According to an aspect of the present disclosure, an organic light emitting display device includes an organic light emitting display panel including a plurality of sub pixels, a pattern buffer layer disposed on the organic light emitting display panel and patterned so as to overlap at least one sub pixel of the plurality of sub pixels, a color filter layer disposed on the pattern buffer layer and including a plurality of color filters corresponding to the plurality of sub pixels, and a black matrix disposed on the same plane as the pattern buffer layer and dividing the plurality of color filters. Accordingly, generation and spread of cracks when the display device is folded may be effectively suppressed. Therefore, the driveability of the display panel and the reliability of the organic light emitting display device may be improved.

Description

technical field [0001] The present disclosure relates to an organic light emitting display device, and more particularly, to an organic light emitting display device having improved folding characteristics and reliability by suppressing generation and propagation of cracks due to folding. Background technique [0002] Unlike a liquid crystal display device (LCD) that includes a backlight, an organic light emitting display device (OLED) does not require a separate light source. Accordingly, the organic light emitting display device can be manufactured to be light and thin with process advantages and low power consumption due to low voltage driving. First of all, an organic light emitting display device includes a self-luminous element and includes a layer formed of an organic thin film, making it more flexible and elastic than other display devices, and thus it is advantageous to be realized as a flexible display device. [0003] Generally, in order to suppress deterioration...
