Abstract:
A liquid crystal display device, comprising:first and second electrode substrates; a liquid crystal layer held between said first and second electrode substrates and partitioned into a plurality of pixel regions in each of which the alignment of liquid crystal molecules is controlled from said first and second electrode substrates; and a reflection plate which is formed on said first electrode substrate and scatters light entering through said second electrode substrate and said liquid crystal layer; wherein said plurality of pixel regions are arrayed in a matrix of rows and columns, said reflection plate has types of projection-recess patterns each of which is separated from another of the same type in at least one of the row and column directions of said pixel regions and includes a plurality of main scattering portions disposed at random and a sub-scattering portion disposed to surround said main scattering portions, said types of projections-recess patterns are assigned to the pixel regions of different display colors, and the average pitch of the main scattering portions of each projection-recess pattern depends on the wavelength of the display color of a corresponding pixel region.
