Abstract
In a transflective type LCD provided with a transparent region and a reflection region in each pixel, when an irregular filmis formed on an active matrix substrateto form irregularities of a reflection electrode film, the irregular filmis specifically formed to almost the same film thickness in both the transparent region and the reflection region to provide substantially the same inter-substrate gap in these two regions so that they may have almost the same V-T characteristics and also the reflection electrode filmmade of Al/Mo is formed so as to overlap with a transmission electrode filmmade of ITO all around an outer periphery of the transmission electrode filmby a width of at least 2 μm, thus suppressing electric erosion from occurring between the ITO and Al substances at the edge of the transmission electrode film
