    Abstract: A flexible display device bendable in a certain direction is realized. R, G, and B pixels are arranged in a mosaic pattern. The display is bendable in a first direction, but is not assumed to be bent in a second direction. A data line extends in the first direction and a select line extends in the second direction. In order to prevent accumulation of distortion in the data line and breakage of the data line when the display is bent in the first direction, the data line is formed into a crank shape. Accordingly, even when the display is bent, an amount of distortion accumulated in the data line corresponds to only a length thereof in the first direction, and therefore, the distortion can be reduced. As a result, breakage of a wire in a flexible display can be prevented.
