Abstract: A method for manufacturing a display device includes forming a plurality of light blocking patterns on a first surface of a transparent substrate, wherein a first light blocking pattern of the plurality of light blocking patterns has a different line width than a second light blocking pattern of the plurality of light blocking patterns. An insulating layer is formed on the first surface of the transparent substrate and the light blocking patterns. A conductive layer is formed on the insulating layer. A photo-resist layer is formed on the conductive layer. The photo-resist layer is exposed with ultraviolet rays through a second surface of the transparent substrate, wherein the first and second surfaces of the transparent substrate are opposite to each other. The photo-resist layer is developed. The conductive layer is etched using the photo-resist layer as a mask. The photo-resist layer is removed.
