Abstract

A display device according to the present invention comprises: a plurality of unit pixels including a main pixel and an auxiliary pixel emitting light of the same color; and a gate driver integrated within each of the plurality of unit pixels and including a plurality of stages, where each of the plurality of stages includes: a scan driving circuit for outputting a first scan signal and a second scan signal; and a light emission driving circuit for outputting a light emission control signal, in which an output timing of a first scanning signal provided to the main pixel is the same as an output timing of a first scanning signal provided to the auxiliary pixel, and wherein an output timing of the second scan signal provided to the main pixel is different from an output timing of the second scan signal provided to the auxiliary pixel. Therefore, even if the main pixel has a defect, the auxiliary pixel can also replace the main pixel to emit light, so that the reliability of the display device aiming at the defect is improved.

Description

technical field [0001] The present invention relates to a gate driver and a display device including the gate driver, and more particularly, to a display device including a gate driver capable of driving main pixels and auxiliary pixels. Background technique [0002] Liquid crystal display devices (LCD) and organic light emitting display devices (OLED), which have been widely used so far, are more and more widely used. [0003] Liquid crystal display devices and organic light emitting display devices are widely used as screens of typical electronic devices such as mobile phones and laptop computers because they can provide high-resolution images and can be made thin. [0004] Disadvantageously, the liquid crystal display device and the organic light emitting display device include a bezel that is visible to a viewer and does not display an image, and thus a display area is reduced due to the size of the bezel. For example, a liquid crystal display device requires a sealant ...
