Abstract

A method for forming a fine exposure pattern where a width and an interval of the pattern are each 1CD, by first exposing a photoresist by using an exposure mask where an interval ratio of a light shielding part and a light transmission part is 2CD:1CD to 4CD:1CD, and then second exposing the photoresist after the exposure mask is shifted at a predetermined interval, or second exposing the photoresist by using an exposure mask formed at a position where a light transmission part is shifted at a predetermined interval, and developing the photoresist, such that it is possible to form a display device having a pixel electrode including a plurality of fine branch electrodes having a smaller width and interval than a resolution of an exposure apparatus.
