摘要： In order to miniaturize a projector as a whole to such a degree that the projector can be included in a small device such as a portable telephone terminal or the like, a red laser light beam (1R) is diffused and shaped by a diffractive optical element (21R) for red, a green laser light beam (1G) is diffused and shaped by a diffractive optical element (21G) for green, and a blue laser light beam (1B) is diffused and shaped by a diffractive optical element (21B) for blue, so as to be each spread over an entire display area of a liquid crystal display panel (40) and be incident on corresponding pixels of a liquid crystal layer (48). The diffused and shaped laser light beams (2R, 2G, and 2B) are made incident on the liquid crystal display panel (40) via a field lens (31). In the liquid crystal display panel (40), red, green, and blue pixels are formed, and a microlens array is formed in an incidence side substrate (41). The liquid crystal display panel (40) distributes and condenses the laser light of the colors by microlenses, and makes the laser light incident on the corresponding pixels. Refraction type optical elements can be used in place of the diffractive optical elements.

摘要： A matrix-addressed type liquid crystal display apparatus having switching devices such as TFTs is provided, featuring that an increased effective voltage can be applied without causing hysteresis in V-T characteristics. Namely, by substantially increasing a value of an applicable voltage in excess of which a display defect starts to appear, a high numerical aperture and a high contrast ratio have been achieved at the same time. In the LCD apparatus of the present invention, a gap between adjacent reverse tilt domains each formed in a portion of a pixel which is arranged corresponding to an arbitrary pixel electrode becomes broader than a minimum gap between adjacent pixel electrodes corresponding thereto, or a thickness of a liquid crystal cell in the portion between adjacent reverse tilt domains is set thinner than a thickness of a liquid crystal cell in the portion of the pixel.

摘要： A method of producing a microlens array includes a patterning step of forming a first optical resin layer having a first refractive index on a transparent substrate and forming a plurality of microlens planes arrayed in a two-dimensional pattern on the front surface of the first optical resin layer; a planarizing step of forming a planarized second optical resin layer; a joining step of providing a support layer on which a transparent protective film is previously formed; and a removing step of removing the support layer in such a manner that only the protective film remains on the second optical resin layer. The planarizing step is performed by filling irregularities of the microlens planes with a resin having a second refractive index and planarizing the front surface, opposed to the microlens planes, of the resin, to form the planarized second optical resin layer, and the joining step is performed by joining the support layer to the planarized second optical resin layer. With this method, a microlens array excellent in surface accuracy and flatness can be produced without the need of provision of a support layer made from glass.

摘要： The invention enables a sufficiently bright color image to be displayed without increasing a heating value with a simple and compact structure which is easily assembled and adjusted. A first microlens for condensing light and a second microlens for changing the travel direction of light are provided, every three pixel electrode parts in a liquid crystal panel. The travel directions of B and G rays condensed by the first microlens are changed by the second microlens, thereby allowing the principal rays to perpendicularly enter the pixel electrode part. The color ray passing through the second microlens focuses on the corresponding pixel electrode part. The first and second microlenses construct a relay optical system having the magnification of 1. Light reflected by the pixel electrode part is transformed by the same first microlens into a parallel ray bundle, and the ray bundle goes out from the liquid crystal panel. The outgoing light of each color ray from the liquid crystal panel is directed toward the incident direction.
