Abstract: In a backlight unit, a plurality of linear light sources arranged in a first direction are accommodated in a case so that they are covered by the case from a side opposite to an illuminated object. In the case, a reflective sheet is disposed on the bottom surface of the case, and a pair of supporting members are disposed to be spaced from each other in the extending direction of the linear light sources. The supporting members support the diffuser plate and the illuminated object. The diffuser plate has, on the light exit surface thereof, a first light-controlling portion having a pattern of stripes parallel to the linear light sources, and a pair of second light-controlling portions extending in the arrangement direction at positions corresponding to the supporting members.

Abstract: A projection display device includes a condensing unit and a shading unit. The condensing unit condenses light emitted from a light source to form a condensed spot on a color wheel. The shading unit, when a size of the condensed spot on the color wheel has increased due to an increase in light emission of the light source, shades a portion of the light passing through the color wheel corresponding to the increased size.

Abstract: The present invention provides a color wheel assembly comprising a color wheel which is divided into plural color regions, and a motor for rotating the color wheel, in which the position of the color wheel can be detected accurately even at high-speed rotation or at elevated temperatures. A Hall IC 27 as a magnetic sensor is provided inside of a motor 2. Every time a detecting magnet 28 which is provided at a rotor part 6 rotates and passes through the Hall IC 27 as the magnetic sensor, a pulse signal is generated by magnetoelectric conversion characteristics of the Hall IC 27, thereby generating a pulse signal for detecting the position of the color wheel 1 only with the color wheel 1 and the motor 2 for rotating the color wheel.
