Abstract: Provided are an organic light emitting display device and a method for manufacturing the same. A color filter is disposed on a substrate. An overcoating layer is disposed on the color filter and includes a plurality of protrusions or a plurality of recesses. The plurality of protrusions and the plurality of recesses are disposed on the color filter to be overlapped with the color filter. A buffer layer for reducing step difference is disposed on the overcoating layer. The buffer layer has a higher refractive index than the overcoating layer and reduces a step difference caused by the plurality of protrusions and the plurality of recesses. An organic light emitting element including an anode, an organic light emitting layer, and a cathode is disposed on the buffer layer. Since the buffer layer has a higher refractive index than the overcoating layer, light extraction efficiency can be increased.

Abstract: There are provided an oxide TFT, a method for fabricating a TFT, an array substrate for a display device having a TFT, and a method for fabricating the display device. The oxide thin film transistor includes: a gate electrode formed on a substrate; a gate insulating layer formed on the entire surface of the substrate including the gate electrode; an active layer pattern formed on the gate insulating layer above the gate electrode and completely overlapping the gate electrode; an etch stop layer pattern formed on the active layer pattern and the gate insulating layer; and a source electrode and a drain electrode formed on the gate insulating layer including the etch stop layer pattern and the active layer pattern and spaced apart from one another, and overlapping both sides of the etch stop layer pattern and the underlying active layer pattern.

Abstract: Disclosed herein is an organic light-emitting display device having a first flexible substrate; a second flexible substrate; a plurality of organic light-emitting pixels on the first flexible substrate and between the first flexible substrate and the second flexible substrate; an encapsulation unit covering the pixels; and an adhesive layer on the encapsulation unit. The Young's modulus of the adhesive layer is equal to or larger than a value so that the first flexible substrate is not deformed by bending stress when it is rolled up.
