Abstract
A liquid crystal display substrate capable of providing good reflection display characteristics, a method of manufacturing the same, and a liquid crystal display device having the same are provided. The liquid crystal display substrate contains a plurality of pixel areas each having a reflection area reflecting light incident from a front surface side of the substrate and a transmission area transmitting light incident from a back surface side of the substrate; a wrinkled resin layer formed with a positive light-sensitive resin in the reflection area and having at least a portion thereof a wrinkled surface; a reflection electrode formed with a light reflection material on the wrinkled resin layer and having a wrinkled surface following the surface of the wrinkled resin layer; and light shielding portions formed as an underlayer of the wrinkled resin layer and shielding light incident from the back surface of the substrate.
