Abstract

A liquid crystal layer (15) is sandwiched between a first substrate (1) provided on a visible side and a second substrate (5) opposed to the first substrate; a first color filter (9) is provided on the first substrate (1) or on the second substrate (5); a transflective reflector (24) is provided on the opposite side to the visible side of the first color filter (9), which transmits a part of light and reflecting almost all the remaining light; and a second color filter (28) is provided on the opposite side to the first color filter (9) with respect to the transflective reflector (24), thereby forming a liquid crystal display panel.
