Thin film transistor substrate and display device including the same

Disclosed is a thin film transistor substrate capable of preventing a circuit from being damaged by static electricity, and a display device including the same, wherein the thin film transistor substrate includes a substrate having a display area for displaying an image, and a non-display area. The circuit is disposed in the non-display area. The circuit includes a first electrode, an insulating film on the first electrode, and a second electrode on the insulating film. An edge of the first electrode facing the display area extends beyond an edge of the second electrode facing the display area. 公开了一种薄膜晶体管基板，其包括：基板，所述基板具有用于显示图像的显示区、以及围绕所述显示区设置的非显示区；和在所述非显示区中的电路部，所述电路部具有薄膜晶体管，所述薄膜晶体管包括第一电极、在所述第一电极上的绝缘膜、以及在所述绝缘膜上的第二电极，其中所述第一电极的边缘与所述第二电极的边缘彼此平行，所述第一电极的边缘延伸超过所述第二电极的边缘。还公开了包括其的显示装置。
