摘要： A microlens array is provided on a light-outgoing side of a monochromic LCD element having a plurality of pixels each corresponding to any one of the three colors R, G, and B. Microlenses of the microlens array respectively correspond to pixel groups each of which is composed of three pixels corresponding to the three colors R, G, and B, respectively. Light fluxes having passed through the microlens array are converged at an entrance pupil position of a projection lens by a field lens and form pixel enlarged images corresponding to the colors R, G, and B. At the entrance pupil position, there is provided a color filter having color regions which respectively correspond to the colors to which the pixel enlarged images correspond. With this arrangement, it is possible to make a diverging angle smaller, at which light passing through the LCD element and the microlens array and being converged on the projection lens by the field lens is diverged. Therefore, there is no need to make the projection lens have a great diameter. As a result, it is possible to provide a projection-type color LCD device having a single-panel arrangement which can be produced at lower costs.

摘要： Particles of a lens coating material for forming a primary film are deposited from a direction toward which the surfaces of the lens prisms of a Fresnel lens face. Next, a light absorbing film is formed, conventionally, by sputtering, on both the lens surfaces on which the previously deposited primary film was formed and on the non-lens surfaces (on which no primary film was formed). This light absorbing film is intended to absorb types of undesirable or "invalid" light (e.g., "flaring light"). Subsequently, the films are removed from only the lens surfaces. Accordingly, a Fresnel lens having "invalid" light absorbing films only on the non-lens surfaces is more easily fabricated within a shorter time and at a reduced cost. Moreover, it is also possible to reduce the generation of "cone" and "rainbow" effects caused by "flaring light" when the Fresnel lens is used as a field lens of a projection-type image display device.

摘要： A method of concealing a bright defect in a transmission display device which displays by selectively transmitting plural beams different wavelength bands shed onto corresponding pixels of a transmission display element through a microlens according to a voltage applied to each pixel is arranged such that only a beam of a wavelength area shed onto a defective luminance point pixel is selectively blocked. On the other hand, the beam shed onto normal pixels surrounding the defective pixel, wherein a bright defect is not generated would be transmitted through the liquid crystal display panel without being blocked. Therefore, the method enables only the defective luminance point pixel to be concealed without affecting the normal pixels, thereby improving a display quality of the transmission display device.

The opposed substrate is constructed by a transparent substrate, microlenses formed on the substrate, a bonding layer, and cover glass. An alignment film and transparent electrodes are formed on the cover glass. The microlenses and the bonding layer are formed by selected resins which have thermal resistance to high temperatures not lower than 150.degree. C., permit heating treatment for forming the alignment film, and satisfy the difference in the refractive indexes between the resins, .increment.n.gtoreq.0.1, so as to enable the microlenses to have a numerical aperture not lower than 0.1. It is thus possible to prevent the decomposition of resins and separation of the microlens in heat treatment and to provide a high-quality, highly reliable liquid crystal display element.
