A method for manufacturing a transflective type LCD having a first substrate provided thereon with a plurality of scanning lines and a plurality of signal lines which are substantially perpendicular to each other and a switching element arranged near each of intersections between said scanning lines and said signal lines, includes forming a reflection region having a reflection electrode film and a transmission region having a transparent electrode film in each pixel surrounded by said scanning lines and said signal lines, a liquid crystal being sandwiched at a gap between said first substrate and a second substrate which is arranged opposite to said first substrate, and forming an organic film having irregularities thereon below said reflection electrode film and said transparent electrode film to substantially the same film thickness.

Transflective type LCD and method for manufacturing the same

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 &#x3bc;m, thus suppressing electric erosion from occurring between the ITO and Al substances at the edge of the transmission electrode film
