Abstract
A liquid crystal display panel in which a signal electrode provided on a first substrate (1), a counter electrode provided on a second substrate (2), and a liquid crystal layer (18) between the substrates, and which carries out display without polarizers by changing the degree of transmission and scattering by means of a voltage applied to a pixel part. A light source part (27) is provided along the periphery of both substrates (1, 2), and a polarization separating device (30) is provided between the liquid crystal panel and the light source part (27).
