Abstract
A liquid crystal display substrate with multiple pixel areas each having in at least a portion thereof a reflection area and a wrinkled resin layer formed with a positive light-sensitive resin in the reflection area. The wrinkled resin layer has in at least a portion thereof a wrinkled surface and a reflection electrode. The wrinkled resin layer also includes a light shielding portion, formed as an underlayer, for shielding light incident from the substrate's back surface side, wherein at least part of the light shielding portion is formed in a same layer with the same material as a drain electrode and a source electrode of a thin film transistor and a storage capacitor electrode, to shield a large proportion of an under area of the wrinkled resin layer from light along with the drain electrode, the source electrode and the storage capacitor electrode.
