发明名称 Color separating and mixing element, video light producing device, and projection type video display
摘要 A color separating and mixing element comprises, in its transparent cube, a first optical function surface formed on a dividing surface for dividing the cube into two triangular prisms and a second optical function surface formed on another dividing surface. The first optical function surface has the function of transmitting both P-polarized light and S-polarized light with respect to red light, has the function of transmitting both P-polarized light and S-polarized light with respect to green light, and has the function of transmitting P-polarized light and reflecting S-polarized light with respect to blue light. The second optical function surface has the function of transmitting P-polarized light and reflecting S-polarized light with respect to red light, has the function of transmitting P-polarized light and reflecting S-polarized light with respect to green light, and has the function of transmitting both P-polarized light and S-polarized light with respect to blue light.
