Abstract
A display device includes a first substrate including pixels and sensing electrodes corresponding with the pixels, and a second substrate facing the first substrate. The second substrate includes an organic layer with a black matrix dividing the pixels and a sensing spacer opposite to the sensing electrode. The organic layer including the black matrix and the sensing spacer may be formed in a single process using organic photoresist material. A mask includes a light-intercepting pattern including slits to block a portion of ultraviolet light emitted towards a photoresist layer to form the black matrix. The mask also includes a pattern to block ultraviolet light in a region corresponding to the sensing spacer if a negative type photoresist material is used, or the mask does not block ultraviolet light in the region corresponding to the sensing spacer if a positive type photoresist material is used.
