Abstract

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.

1. 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, comprising:

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, comprising:

forming a first organic film as scattered in dot;

performing predetermined heat treatment to form protrusions; and

covering moderately by a second organic film to form said predetermined irregularities.
