Abstract
A liquid crystal display panel for a timepiece comprises: a polymer dispersed liquid crystal cell (10) which is structured by respectively forming an opposed electrode (2) on a first substrate (1) of a pair of transparent substrates and a signal electrode (4) on a second substrate (3), and sealing a liquid crystal layer (5) containing a liquid crystal and a polymer material between the first substrate (1) and the second substrate (3) to form pixel portions at intersections between the signal electrode (4) and the opposed electrode (2); a reflector (15) which transmits a portion of light, placed on the side of a face, on which the opposed electrode (2) is not formed, of the first substrate (1); and an auxiliary light source placed on the outer side of the reflector (15), so that time information can be displayed with good visibility even when the auxiliary light source is turned off.
