Abstract:
1. A method of manufacturing an in-plane-switching mode liquid crystal display device, comprising: sequentially forming a conductive layer and a photo resist film on a substrate; aligning a photo mask with a mask pattern for a fine pattern formation over the substrate covered with the photo resist film; patterning the photo resist film by performing an exposing process using the photo mask and a developing process; and forming an electrode by etching the conductive layer using the photo resist pattern as an etch mask, wherein the photo mask includes a mask substrate and mask patterns disposed between opposite first and second side ends on the mask substrate, wherein the mask pattern for the fine pattern formation is formed to include a plurality of unit mask patterns arranged in a single line, and each of the unit mask patterns is configured to include a body portion positioned at a center and wing portions formed in a triangular shape at both sides of the body portion, and wherein the body portion is formed to have a length corresponding to a ratio of 2:1 to a height of the wing portion, and the wing portion of the triangular shape is formed to have an apex angle of substantially 90°.
