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.

A liquid crystal display panel, comprising:
- a first substrate provided on a visible side;
- a second substrate opposed to said first substrate;
- a liquid crystal layer sandwiched between said first substrate and said second substrate;
- a first color filter provided in-between said first substrate and said second substrate;
- a transflective reflector, provided on an opposite side to said visible side of said liquid crystal layer and said first color filter, for transmitting a part of light and substantially reflecting all the remaining light;
- and
- a second color filter provided on an opposite side to said first color filter with respect to said transflective reflector;
- wherein said transflective reflector is provided on an opposite side to said visible side of said second substrate, and said second color filter is provided on an opposite side to said second substrate with respect to said transflective reflector.
