Abstract
A display device includes a substrate and pixels arranged on the substrate in a matrix form. The substrate includes a display area in which the pixels are arranged and a non-display area disposed adjacent to a side of the display area. Each pixel includes a cover layer that extends in a row direction that includes a sidewall portion connected to the substrate and a cover portion spaced apart from the substrate and connected to the sidewall portion to define a tunnel-shaped cavity on the substrate. A width of the sidewall portion between adjacent pixels is less than a width of the sidewall portion disposed at an outermost position, and the cover layer seals one side of the tunnel-shaped cavity in the pixels arranged in a first row and a last row.
