A method of manufacturing a thin film transistor is disclosed. In one aspect, the method includes forming an active layer over a substrate and forming a gate insulating layer containing a dopant over the active layer. The method also includes irradiating laser light onto the gate insulating layer such that the dopant of the gate insulating layer diffuses into the active layer.

Method of manufacturing thin film transistor

A display device having active level shift (ALS) lines and ALS drivers connected to the ALS lines removed from the display device, and a gate line at a rear end pixel area is used instead of the ALS line to obtain the effect of the ALS lines. Accordingly, a pixel aperture ratio may be increased and a width of an outer black matrix may be reduced.
