PURPOSE:To improve transmitivity by coloring transmitted light without using a color filter and thereby to satisfactorily enhance the display brightness. CONSTITUTION:The device is provided with a liquid crystal cell 30 in which liquid crystal molecules 38a are homogeneously oriented, one sheet of phase plate 40, one sheet of polarizing plate 41 and a reflecting plate 42. The polarizing plate 41 is arranged at a front side of the liquid crystal cell 30, the reflecting plate 42 is arranged at the rear side of the liquid crystal cell 30 and the phase plate 40 is arranged between the polarizing plate 41 and the liquid crystal cell 30. A lagging axis of the phase plate 40 and a liquid crystal molecule orientation direction of the liquid crystal cell 30 are disposed approximately parallel to each other or intersecting orthogonally with each other and a transmission axis of the polarizing plate 41 is inclined at a prescribed angle to the lagging axis of the phase plate 40. |
