Abstract: A liquid crystal display apparatus includes a light source, a light source drive circuit for switching the light source on and off, a heat release member for releasing heat generated by at least one of the light source drive circuit and the light source, and a heat transport member for transporting the heat to the heat release member. The light source drive circuit is connected to the heat release member through the heat transport member. The heat transport member has high heat conductivity so that a large part of the heat can be transferred to the heat release member through the heat transport member for a short time. Thus, the heat transport member prevents the heat from affecting components disposed near the light source drive circuit or the light source.

Light emitted from the module is efficiently utilized for illuminating the scale plate by positioning the module at a right position with respect to the light-conducting plate.

Abstract: An indicating instrument for a vehicle has a display board, a light modulation member disposed to cover a surface of the display board. An illumination intensity of the display board is detected by a light detecting member and a control unit applies to a dc pulse voltage to the light modulation member, to thereby control a light transmissivity of the light modulation member according to the illumination intensity. When the illumination intensity is higher than a predetermined level, the voltage is applied in one direction so that the light modulation member changes from a colorless condition to a colored condition to restrict an external light from reflecting on the display board. When the illumination intensity is lower than a predetermined level, the voltage is applied in a reverse direction so that the light modulation member is transferred from the colored condition to the colorless condition to maintain the visibility of the display board.
