摘要： An optical shifter includes first and second optical shifting sections, each of which can transmit an incoming light ray after having shifted its optical axis and which are arranged such that a light ray transmitted through the first optical shifting section enters the second optical shifting section. Each of the shifting sections includes: a liquid crystal element including a liquid crystal cell, which selectively changes the polarization direction of the incoming light ray responsive to a voltage applied thereto; and a birefringent element, which receives the light ray transmitted through the liquid crystal element and which exhibits one of different refractive indices according to the polarization direction of the incoming light ray. The magnitude of shift caused by the first optical shifting section between the optical axes of the incoming and outgoing light rays is substantially twice greater than that of shift caused by the second optical shifting section.

摘要： A liquid crystal display element, which is installed in a projection-type color liquid crystal display, is provided with the first glass substrate. The first glass substrate is provided with the first micro-lens array on its light-incident side and the second micro-lens array on its light-releasing side. The first micro-lens array converges light beams of respective primary colors onto the vicinity of the light-releasing position on the second micro-lens array. The second micro-lens array makes the incident light beams parallel to each other and releases them from the liquid crystal display element. Thus, even in the case of using a projection lens having a small diameter, it is possible to improve the efficiency of utilization of light. Moreover, this arrangement eliminates the necessity of having to employ a comparatively expensive projection lens with a large diameter, thereby reducing the costs of production.
摘要翻译：安装在投射型彩色液晶显示器中的液晶显示元件设置有第一玻璃基板。第一玻璃基板在其光入射侧设置有第一微透镜阵列，在其光释放侧设置有第二微透镜阵列。第一微透镜阵列将各原色光束会聚在第二微透镜阵列上的光释放位置附近。第二微透镜阵列使入射光束彼此平行并将它们从液晶显示元件释放。因此，即使在使用具有小直径的投影透镜的情况下，也可以提高光的利用效率。此外，这种布置消除了必须使用具有大直径的相对昂贵的投影透镜，从而降低了生产成本。

摘要： The present invention provides a lighting device including a light source; a reflecting mirror for reflecting light emitted by the light source in a determined direction; and a compensating element for receiving the light from the reflecting mirror and allowing the light to outgo in the form of parallel rays. Further, a projection type image display system including the above-mentioned lighting device and a display element for forming an image by receiving light from the lighting device is provided. According to the present invention, light can be emitted with a satisfactory degree of parallelization and an even illuminance, constant irregularity due to the photoelasticity can be degraded, and the degradation in brightness of a projected image due to a low ratio of aperture can be avoided. Thus, a uniform image with no illuminance irregularity can be projected.

摘要： A projection-type image display device includes a transmissive image display panel having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array for converging light emitted by a light source onto the transmissive image display panel. The planar microlens array comprises a substrate and a matrix of microlenses disposed on the substrate for converging the light onto the pixels, respectively, each of the microlenses being of an oblong shape. Each of the microlenses may have a longitudinal axis inclined with respect to an axis of the matrix of pixels to cover the pixel aperture of one of the pixels. The oblong shape of each of the microlenses may be composed of a pair of spaced identical semicircles and a rectangle interconnecting the identical semicircles and having sides of the same length as the diameter of the semicircles. Since the oblong microlenses are shaped to fully cover the pixel apertures of the corresponding pixels, the light from the light source is efficiently converged onto the pixels by the microlenses to produce light display images.

摘要： An optical shifter includes at least one liquid crystal cell and a birefringent element. The liquid crystal cell has a first surface to receive light thereon and a second surface to pass the light therethrough and selectively changes polarization states of the light according to a voltage applied thereto. The birefringent element receives the light that has gone out of the liquid crystal cell through the second surface thereof, and selectively shifts the optical path of the light depending on the polarization state of the light. The optical shifter controls the temperature of the liquid crystal cell by way of at least one heat transfer member, through which heat can be transferred to/from the first surface and/or the second surface of the liquid crystal cell.
