摘要： According to a liquid crystal panel of the present invention, the focal length of micro-lenses is set to be longer than the distance between the micro-lens array and the first substrate, while light collected by each micro-lens is arranged to focus inside the first substrate. Thus, the divergence angle after focusing can be reduced. Therefore, the maximum light-emerging angle from the LCD panel can be reduced, and eclipse of the light which causes chrominance or luminance non-uniformity does not occur even when a lens having a high F number is used as a projection lens.

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.

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： 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： Laser light beams are diffused and shaped by diffractive optical devices such that they are introduced to corresponding pixels of a liquid crystal layer over an entire area of a display region of a reflective liquid crystal panel. The diffused and shaped laser light beams are introduced to the reflective liquid crystal panel through a field lens and a polarizing beam splitter. Red, green and blue pixels are formed on the reflective liquid crystal panel, and a microlens array is formed on an incoming and outgoing side substrate while reflecting layers corresponding to the pixels are formed on a reflection side substrate. The laser light fluxes of the colors are distributed and condensed by the microlenses and introduced to the corresponding pixels and then reflected by the corresponding reflecting layers. Refractive optical devices may be used in place of the diffractive optical devices.
