Filed: 2000-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of TFTs due to electricity generating in acceptance of light by disposing a 1/4 wavelength layer which transmits light as circularly polarized light, a color filter which transmits one of circularly polarized light components, and a dichroic layer for circularly polarized light. SOLUTION: This device has a 1/4 wavelength layer 22 which shifts the phase of the linearly polarized light entering from a liquid crystal layer 20 by π/2 to produce and to transmit circularly polarized light, a color filter 24 which transmits one circularly polarized light component of the right-handed or left-handed rotation directions and reflects the other circularly polarized light component, and a light-absorbing dichroic layer 30 for circularly polarized light which transmits the transmitted circularly polarized light component in the right or left rotation direction and which absorbs the other circularly polarized light component. The dichroic layer 30 for circularly polarized light is a light-absorbing type so that when external light (nonpolarized light) enters the surface of the dicbroic layer 30 for circularly polarized light, 50% of the light is absorbed.  Therefore, even when TFTs are formed in the liquid crystal layer side, the quantity of accepted light can be decreased so that malfunction of TFTs due to the electricity generating in acceptance of light can be suppressed.
