Abstract: 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.

Abstract: In a method of manufacturing semiconductor chips for display, a semiconductor thin film is first formed on an insulating substrate, and then a series of processes including a heat-treatment process for the semiconductor thin film are carried out to form integrated thin film transistors on a sectioned area for one chip. Thereafter, pixel electrodes for one picture (frame) are formed within the sectioned area. During the series of processes, a laser pulse is irradiated onto the sectioned area by one shot to perform a heat treatment on the semiconductor thin film for one chip collectively and simultaneously (i.e., perform a batch heat treatment on the semiconductor thin film). Through the batch heat treatment, the crystallization of the semiconductor thin film is promoted. In addition, after the semiconductor thin film is doped with impurities, the activation of impurities doped in the semiconductor thin film can be performed by the batch heat treatment.

Abstract: 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.

Abstract: To provide a liquid crystal display device and manufacturing method thereof for preventing a drop in the pixel slot opening and focus rates due to poor alignment precision of the drive substrate and microlens which face each other, and for improving the focus rate and production efficiency. A lens group comprised of a plurality of microlenses is integrated into the opposing substrate. A second alignment mark is formed at the desired position within the display area on the opposing substrate. This second alignment mark is formed along grooves between numerous protrusions having a semi-circular shaped cross section so the outer contours of the face form a cross shape of a specific width. These protrusions are made of the same material (for instance transparent plastic) and shape (semi-circular cross section) as those of the microlens at the display area, forming a lens shape.

Abstract: The invention provides a small-sized high-resolution transmissive display device which can be employed in a projector of the color-filterless type. The transmissive display device includes a pair of transparent substrates connected to each other via a predetermined space. The transparent substrates are provided with electrodes forming pixels arranged in a matrix form. The above-described space is filled with an electrooptical material so that the transmissivity of an incident light ray is modulated by the electrooptical material for each pixel and thus converted into an emerging light ray. The transparent substrate on the incident side is further provided with micro lenses and micro prisms. The incident light ray includes three primary color components which have been separated so that they enters the transparent substrate at angles different from each other.
