Abstract

Disclosed is a trans-reflective type LCD device and a method for fabricating the same wherein the method reduces the required number of masks by using a half-tone mask and a diffraction exposure process. Further, by using a half-tone mask and diffraction exposure process, a desired uneven surface may be formed on the reflective part of the pixel region without resorting to thermal processes that may otherwise degrade an insulating layer under the reflective electrode. Accordingly, an organic insulating material may be used between the transmissive electrode and the reflective electrode.
