摘要： There are provided a spatial light modulation device and a projector capable of obtaining smooth image quality so that an observer does not recognize any light shading portion such as a black matrix. The projector includes a spatial light modulation device (110R) for modulating the incident light according to an image signal and emitting the modulated result and a prism group (210) arranged at the emission side of the spatial light modulation device (110R). The spatial light modulation device (110R) has an opening (230) as a plurality of pixel portions arranged in a matrix and a black matrix (220) arranged between them. The prism group (210) consists of a prism element (211) having at least a refraction surface (212). Light from one opening (230) is introduced into at least a part of the prism group (210). The direction of the refraction surface and the inclination angle ϑ are defined so as to introduce an opening image (230P) onto a black matrix portion image (220P) on a screen (116) at a predetermined distance L from the prism group (210).

摘要： A micromachine and a method of manufacturing the same which are suitable as or for a micromachine having a first dynamic fine structural portion constituting a driving portion, and a second static fine structural portion performing a switching function or a function of an optical element, the method comprising forming the second static fine structural portion on the first dynamic fine structural portion, or superposing the second static fine structural portion thereon and die transferring the same thereto, whereby the method enables the second fine structure to be formed without using at least a complicated step, such as a silicon process in an intermediate stage of the method, and into a complicated shape easily with a high reproducibility, and contributes to the improvement of the productivity. Especially, when a plurality of elements are arranged in an arrayed state as in a spatial light modulator, the die transfer techniques enable the second fine structure to be reproduced stably as compared with the techniques using a silicon process for forming all parts of a micromachine, whereby the subject method reduces the probability of occurrence of defects to a remarkably low level and contributes to the improvement of the yield.

摘要： An image display apparatus 100 that displays an image using a light modulated according to an image signal includes a projection optical system 90 that includes a projection lens 20, a first mirror 30 that reflects a light from the projection lens 20, and a second mirror 40 that widens an angle of a light from the first mirror 30 by reflecting the light, and projects the light modulated according to the image signal from an optical engine unit 10; a third mirror 50 that reflects a light from the projection optical system 90; and a screen 60 that transmits a light from the third mirror 50. The projection lens 20 and the second mirror 40 are arranged in such a manner that an optical axis of the projection lens 20 substantially matches an optical axis of the second mirror 40, and shift the light from the optical engine unit 10 to a specific side from the optical axis of the projection lens 20. It is possible to cause a light to travel accurately, to display an image, in a thin structure with a small non-display section adjacent to a screen.

摘要： A light guide part which can reflect a light totally and transfer the light, an optical switching part which has its extraction plane close to a totally reflective plane to capture an evanescent light and reflects and emits the evanescent light and a driving part which drives the optical switching part are layered in the direction of the light emission in this order to obtain an optical switching device with a hierarchical structure. By employing the hierarchical structure, the respective layers can be optimized. Especially, as the extracted light is not passed through the driving part, the driving part can be optimized to provide an optical switching device which can operate at a high velocity and with a low power consumption. Therefore, an optical switching device which shows the low loss of a light utilizing an evanescent wave, has a high response velocity and, further, shows a large contrast ratio can be provided.
