发明名称 Display device and method of manufacturing the same
摘要 A display device and a method of manufacturing the same are disclosed, in which a sensing electrode for sensing a touch of a user is built in a display panel, whereby a separate touch screen is not required on an upper surface of the display panel and thus thickness and manufacturing cost are reduced.

主权项 1. A method of manufacturing a display device, the method comprising: sequentially forming a first material layer for forming a semiconductor layer and a source/drain electrode layer on a surface of a substrate on which a gate electrode and a gate insulating film are formed; simultaneously patterning the first material layer and the source/drain electrode layer to form a first pattern in a thin film transistor region and to form a second pattern in a data pad region, the first pattern comprising a first portion of the semiconductor layer and a first portion of the source/drain electrode layer, and the second pattern comprising a second portion of the semiconductor layer and a data pad formed from a second portion of the source/drain electrode layer; sequentially forming first and second passivation films structured such that a hole exists through the first and second passivation films through which at least a part of the source/drain electrode layer is exposed in the thin film transistor region including the first pattern; sequentially forming a second material layer and a third material layer on the second passivation film; forming a sensing line pattern, a pixel electrode pattern, and a connection electrode pattern connected with the data pad by patterning the second and third material layers through a patterning process using a half tone mask; forming a third passivation film on the sensing line pattern, the pixel electrode pattern, and the connection electrode pattern; and forming a common electrode connected with the sensing line pattern and forming a data pad electrode connected with the connection electrode pattern on the third passivation film.
