DISPLAY DEVICE AND ELECTRONIC DEVICE INCLUDING THE SAME

原文（中国語）

A display device includes: a base layer; a pixel; a signal line electrically connected to the pixel; and a signal pad connected to the signal line. The signal pad includes: a first conductive pattern connected to an end portion of the signal line; an insulating pattern on the first conductive pattern; a second conductive pattern contacting the first conductive pattern, and including a portion on a part of an upper surface of the insulating pattern; and a third conductive pattern on the first conductive pattern, and including a portion overlapping with the portion of the second conductive pattern. A partial area of the upper surface of the insulating pattern is exposed from the second conductive pattern and the third conductive pattern, and the end portion of the signal line is connected to the first conductive pattern through a first contact hole defined in a first group of insulating layers.
