Abstract
In a projection type color liquid crystal display apparatus, a polarization conversion section receives a luminous flux from a light source to convert the luminous flux into a unified luminous flux having a single linearly-polarized direction. A color separation section receives the unified luminous flux to selectively reflect a plurality of color components of the unified luminous flux individually at different angles. Convex lenses of a microlens array converge the reflected color components into different pixels of a liquid crystal element.
