摘要： PROBLEM TO BE SOLVED: To provide a projector capable of improving the number of pixels in a pseudo-manner by shifting pixels, and suppressing deterioration of picture quality such as an occurrence of a ghost image caused by unintended reflected light and a decrease in ANSI contrast.SOLUTION: In a first retardation plate 28a, image light in a state of linear polarization through a light emission side polarizer 25h can be brought into a state of circular polarization. Thereby, of the image light, the light reflected at a polarization switching liquid crystal panel 28b proceeds in reverse direction at the first retardation plate 28a again, so that the light, which has proceeded in reverse direction and passed through the first retardation plate 28a, becomes polarization orthogonal to a polarization axis that is a transmission axis of the light emission side polarizer 25h. Therefore, the occurrence of a ghost image caused by the reflection at the polarization switching liquid crystal panel 28b and the decrease in ANSI contrast can be suppressed, and a high quality image can be formed.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of suppressing contrast deterioration of a display image even when dust-proof glass is replaced with crystal materials such as a crystal plate. SOLUTION: Since the direction of an absorption axis of a polarizing filter 25e on the incident side perpendicularly cross the direction of an optical axis of a dust-proof plate 74a on the incident side formed of a positive uniaxial crystal materials, a light flux which is made incident in a state of being in parallel with a system optical axis SA is not subjected to a birefringence behavior by the dust-proof plate 74a on the incident side in passage of the polarizing filter 25e. Thus, a phenomenon in which modulated light with a shifted modulation amount is injected by refractive index anisotropy of the dust-proof plate 74a on the incident side while raising cooling efficiency by the dust-proof plate 74a on the incident side is suppressed. Furthermore, it is thought that the light flux which is made incident in an inclined state to the system optical axis SA is offset with a birefringence behavior to be generated in a liquid crystal panel 26a even when the light flux is subjected to the birefringence behavior by the dust-proof plate 74a on the incident side in a liquid crystal light bulb 25a.

摘要翻译：解决的问题：提供一种能够抑制显示图像的对比度劣化的液晶显示装置，即使用诸如晶体板的晶体材料代替防尘玻璃。解决方案：由于入射侧的偏振滤光器25e的吸收轴的方向垂直于由正单轴晶体材料形成的入射侧的防尘板74a的光轴方向垂直，所以光在与系统光轴SA平行的状态下入射的磁通在偏振滤光器25e的通过中不受到入射侧的防尘板74a的双折射性。因此，通过入射侧的防尘板74a的折射率各向异性注入偏移调制量的调制光，同时通过入射侧的防尘板74a提高冷却效率的现象被抑制。此外，认为即使当光通量受到双折射行为时，即使在光束受到双折射行为时，也会以液晶面板26a中产生的双折射特性来偏移以倾斜状态入射到系统光轴SA的光束在液晶灯泡25a中的入射侧的防尘板74a。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a projector capable of adjusting contrast of a liquid crystal light valve itself when adjusting illuminating light quantity.
SOLUTION: By setting a light shielding member 51 at an operation position, intercepted light quantity is relatively increased in terms of inclined luminous flux in a middle direction in ±X-axis direction and ±Y-axis direction. Since the ±X-axis direction and the ±Y-axis direction are directions where the contrast of the liquid crystal light valve 31 is excellently maintained as to a direction where illuminating light is inclined, the contrast of a projection image formed on a screen through a projection lens 29 is relatively improved in comparison with a case where the light shielding member 51 exists at a retreat position as the intercepted light quantity in the middle direction is increased by the light shielding member 51 arranged at the operation position.
