Title: Polarization illuminator and projection type display device using the same
Inventor: KURAMOCHI JUNKO
IPC: G02F1/13
Filed: 1992-01-17
Abstract: PURPOSE:To obtain the projection type display device whose light utilization efficiency is high by forming a light emitting part of a light source in a non-spherical shape whose vertical/ horizontal length are different from each other, and installing the longitudinal direction of the non-spherical light emitting part in the direction being vertical to a plane containing a normal and an optical axis on the working surface of a polarization beam splitter. CONSTITUTION:A light source 11 uses that of a shape of a non-spherical body in which vertical/horizontal length of a light emitting part are different from each other, and is arranged so that the major axis direction of the light emitting part coincides with the (y) axis direction. In general, as for a polarization separation characteristic of a multi-layer film of a polarization beam splitter, characteristic deterioration caused by incident angle dependency is smaller in spreading in the (y) direction than in spreading in the (x) direction. Accordingly, by taking a spreading angle of light in the (x) axis direction, and a spreading angle in the (y) axis direction so as to be small and large, respectively, a polarized light whose polarization ratio is high, and also, a high luminance image whose light utilization efficiency is high can be formed, compared with a usual example having a light source of the same light emission quantity. Also, the light emitting part of the light source 11 in which distance between electrodes can be taken long, can be manufactured easily, and becomes a lamp of a long service life.
