Manufacturing method of a panel for liquid crystal
First Claim
1. A method of manufacturing a liquid crystal display by divisionally exposing an active area with a plurality of shots including first and second shots adjacent to each other, the method comprising:
- preparing a stitch area which is an overlapping area of the first and the second shots at a boundary between the first shot and the second shot; and
performing gradual decrease of an area for the first shot and gradual increase of an area for the second shot in the stitch area along a direction from the first shot to the second shot, wherein the decrease of an area for the first shot and the increase of an area for the second shot are preformed by unit of a unit stitch area obtained by dividing a pixel area into at least two parts.

Abstract
In a method of manufacturing a liquid crystal display using a divisional exposure for a substrate, an overlapping area at the boundary between adjacent shots is provided and the shots left and right to the boundary are exposed in a way that the areas of the shots gradually decreases and gradually increases, respectively, to reduce the brightness difference due to stitch errors between the two shots. For example, the number of unit stitch areas assigned to the left gradually decreases and the number of unit stitch areas assigned to the right shot gradually increases as it goes to the right along the transverse direction in the stitch area. A unit stitch includes an area obtained by dividing a pixel into at least two parts.
