摘要： An optical block, which may be of a small size, for applying light efficiently to a display device such as a liquid crystal panel, and a display apparatus. The optical block (1) has a polarizing beam splitter (3) mounted on baseboard (2) at a predetermined angle with respect to light applied from a light source (10), for passing a P wave toward an exit side and reflecting an S wave, reflecting device (4) mounted on the baseboard (2) for reflecting the reflected S wave toward the exit side, and plane-of-polarization rotating device (5) mounted on the baseboard (2) for rotating the plane of polarization of the S wave reflected toward the exit side. The display apparatus has a light source (10), a first multilens array (12), the optical block (1), a second multilens array (13), separating device (14, 19) for separating emitted light into red light (R), green light (G), and blue light (B), light modulating device (17, 21, 26) for generating modulated red light, modulated green light, and modulated blue light based on the separated light, and emitting device (18) for combining the modulated red light, modulated green light, and modulated blue light and emitting combined modulated light. The optical block is of a thin structure so that it may be a space saver and lightweight. Optical paths from the light source to liquid crystal panels or the like may be reduced to reduce the size of the display apparatus.

摘要： A projection type display apparatus which allows a reduction in size and which enables images to be clearly projected. In a projection type display apparatus 1 in which an image displayed by an image display device 53 is projected onto a screen by using light from a light source 3, the light from the light source 3 is transmitted through an optical element as illuminating light and guided along a first optical axis OP1 before it is reflected by a first reflecting mirror; and the illuminating light is reflected by a second reflecting mirror and guided toward the image display device 53 along a second optical axis OP2. The first optical axis OP1 and the second optical axis OP2 are arranged at different positions and parallel to each other. Arranged in the first optical axis OP1 is an optical element for concentrating the intensity distribution of the illuminating light, and the optical element is formed by two-dimensionally arranging a plurality of unit lenses. The ratio of the size d of the unit lens to the size D of the image display device 53, d/D, is set to be as follows:1/16.ltoreq.d/D.ltoreq.1/7
