摘要： A liquid crystal display includes an illumination optical system which has a light source for emitting light and acts to irradiate the light from the light source on a light bulb on which an optical image is formed in accordance with a video signal, and a transmission-type liquid crystal display element for displaying the image information by the electrooptical effect of the liquid injected between a pair of transparent substrates of the light bulb. The liquid crystal display element is formed of a micro-lens array which has unit lenses provided to oppose the respective picture elements of the picture element array of the liquid crystal and thus to have the same array as the picture element array of the liquid crystal. Since this micro-lens array is closely attached to the side of liquid crystal display element to which the luminous flux emitted from the light source is incident, or integrally formed within the liquid crystal cell substrate, the liquid crystal display element has a high aperture ratio.

摘要： A bulb (4) of lamp (1) has a reflection film (2) or reflection mirror (9) to make light components going outside a reflector (3) direct to the reflector (3) to reflect. If the lamp (1) is a spot light source, a light emission center is positioned at a center of spherical reflection mirror (9). If the lamp (1) is not a spot light source, the reflection mirror (9) is made ellipsoid and at its two focal points, ends of two light emitting electrodes are positioned. Also, the lamp (1) having the reflection mirror (9) is used in the illumination unit for a liquid crystal display apparatus to increase the brightness of the image projected onto the screen (26). Further, the liquid crystal display device (23) has within a liquid crystal display device (23) a microlens array for collecting the incoming light into an area of each picture element electrode (39) to increase the light utilization efficiency of the liquid crystal display device (23).

摘要： A liquid crystal display includes an illumination optical system which has a light source of emitting source on a light valve on which an optical image is formed in accordance with a video signal. A transmission-type liquid crystal display element is used to display the image information by the electrooptical effect of the liquid injected between a pair of transparent substrates of the light valve. The liquid crystal display element is formed of a micro-lens array which has unit lenses provided to oppose the respective picture elements of the picture element array of the liquid crystal and thus to have the same array as the picture element array of the liquid crystal. The micro-lens array is proximate to the side of liquid crystal display element to which the luminous flux emitted from the light source is incident, or integrally formed within the liquid crystal cell substrate so that the liquid crystal display element has a high aperture ratio. The light source or the concave mirror is shaped similar to the shape of the aperture of the liquid crystal display element.
