Organic light emitting display device

摘要

Disclosed herein is an OLED (Organic Light Emitting Display) device. A switching thin-film transistor configured to be an oxide semiconductor thin-film transistor is disposed in a first pixel. A second pixel is adjacent to the first pixel in the direction in which data lines are extended. A switching thin-film transistor configured to be an LTPS (Low Temperature Poly-Silicon) thin-film transistor is disposed in the second pixel. The switching thin-film transistor of the first pixel and the switching thin-film transistor of the second pixel are connected to the same gate line. A pixel and another pixel adjacent to the pixel connected to a gate line in common, so that it is possible to provide an OLED device with high aperture ratio and high resolution.
