<p>A unit reflecting area (13) comprising one or more projections/recesses (17) is formed on the reflecting plate (11). Light is made to fall on the reflecting plate (11), and part of the light reflected from the unit reflecting area (13) is outputted toward the whole ringlike predetermined area (output area (14)) defined on a predetermined flat surface. The output area (14) is so defined that the light specularly reflected from a liquid crystal panel (18) overlaps with a discoloration area (15) as little as possible. Such a reflecting plate used for a display of reflection type or of semitransmission type has an improved efficiency of use of incident light by decreasing the useless light reflected in the useless direction.</p> |
