タ。 A light source that emits light source light, three liquid crystal panels that display a color image to be projected onto a screen corresponding to each component of R, G, and B, and a light source that emits R, G, and B light source light.
A reflection system consisting of a plurality of mirrors that separates into each component, projects only the corresponding component onto the liquid crystal panel, and superimposes each component that has passed through each liquid crystal panel to form an image light; In a liquid crystal projector that has a condensing lens provided on the incident side and projects the image light onto a screen to display the color image, R, G, and B components are adjusted for the purpose of color correction of the light source light. A liquid crystal projector characterized in that a one- or two-component liquid crystal panel and a condenser lens therein are coated with an anti-reflection coating.
