  • Production process of a display device, and a display device
    Patent number: 7898641
    Abstract: A production process of a display device is performed such that, even if exposure displacement is caused by an error in stitching divided regions, a linear protrusion in the vicinity of a divisional boundary is prevented from becoming thin or disappearing because of double exposure. The display device having an insulating substrate on which a plurality of dots are arranged in a matrix includes a linear protrusion which is formed on the insulating substrate by performing divisional exposure on a plurality of divided regions on the insulating substrate, wherein the boundary between the adjacent divided regions provides, in the vicinity of the linear protrusion in one of the divided regions, at least a bent portion that extends into the other divided region at a predetermined distance.
