Problems solved by technology
However, the polarizer is an expensive element and has a relatively large thickness, making it unsuitable for thickness reduction
In addition, there is a problem in that the polarizing plate also partially absorbs light emitted from the organic light-emitting layer, thereby lowering the luminous efficiency.

Abstract
Disclosed are an organic light emitting display device and a method for manufacturing the same. The organic light emitting display device includes a transparent base member, a touch sensor which includes a touch electrode disposed above the transparent base member and a touch protection layer which covers the touch electrode, a black matrix which is disposed below or above the touch sensor and defines a plurality of opening areas, a plurality of color filters disposed on the same plane as the black matrix and corresponds to the plurality of opening areas, a first buffer layer disposed above the upper one of the touch sensor and the plurality of color filters, a thin film transistor disposed above the first buffer layer, and an organic light emitting element which is disposed above the thin film transistor and corresponds to the plurality of opening areas.
Description
technical field [0001] The present invention relates to an organic light emitting display device, and more particularly, to a bottom emission type organic light emitting display device including a color filter and a touch sensor and a manufacturing method thereof. Background technique [0002] An organic light emitting display device (OLED) does not require a separate light source, unlike a liquid crystal display device (LCD) that includes a backlight. Accordingly, the organic light emitting display device can be manufactured thin and light, has process advantages, and has 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 flexibility and elasticity superior to other display devices, and thus is advantageously realized as a flexible display device. [0003] In general, an organic light-emitting display device is a display device...
