Abstract
A liquid crystal display device comprises array and counter substrates, a liquid crystal layer held between the array and counter substrates and partitioned into a plurality of pixel regions in each of which the alignment of liquid crystal molecules is controlled from the array and counter substrate, and a reflection plate which is formed on the array substrate and scatters light entering through the counter substrate and the liquid crystal layer. Particularly, the plurality of pixel regions are formed in an approximately matrix manner, and the reflection plate includes types of projection-recess patterns each separated from another of the same type in at least one of the row and column directions of the pixel regions.
