Abstract: A display device includes a window module disposed on a display module. The display module has a peripheral region disposed on at least one side of an active region. The window module includes a pattern layer disposed adjacent to a window and overlapping the active region and the peripheral region. The pattern layer includes a transparent portion and a discoloration portion having a light transmittance lower than that of the transparent portion. Each of the transparent portion and the discoloration portion includes a discoloration inducer activated by a laser, so that the display device exhibits good display quality and excellent reliability properties.
