A liquid crystal projector device of the present invention includes a lamp unit, an optical system for separating light emitted from the lamp unit into light of three primary colors, and an image synthesizer for generating image light of three primary colors from the light of three primary colors, and synthesizing the generated image light of three primary colors into color image light. The image synthesizer includes three liquid crystal panels for three primary colors and three incidence polarizing plates arranged at light incidence sides of the liquid crystal panels. Each of the incidence polarizing plates includes a glass base material and a polarizing film joined to a surface thereof. The surface area ratio of the glass base material to the polarizing film is set to 178%.
