Abstract

A display panel includes a base substrate in which an active area and a peripheral area adjacent to the active area are defined, a pixel disposed in the active area, a first line disposed in the active area and connected to the pixel, a second line disposed in the peripheral area and spaced apart from the first line in a plan view, a linking pattern electrically connecting the first line to the second line and disposed on a layer different from a layer on which each of the first and second lines is disposed, and an inorganic layer disposed between the first line and the linking pattern and between the second line and the linking pattern. The linking pattern is connected to the first line and the second line through contact holes formed in the inorganic layer.
