Abstract: A light source apparatus has two or more light sources that have different light-emission spectra and that can be controlled independently, and also has light sensors for detecting the quantity of light emitted by the light sources. The light sensors are composed of one type of light sensor that is not provided with a color filter for selecting the wavelength of received light, and the light sensors are sensitive to wavelength ranges that are sufficiently broad to simultaneously receive light in red, green, and blue wavelength ranges. A control circuit controls the two or more light sources to emit light in a time sequential fashion, and compares reference data with the output values of the light sensors to control the quantity of light emitted by the light sources by means of a light source drive circuit. It is thereby possible to reduce the cost and size of a light source apparatus that is capable of correcting changes in hue.

Abstract: A liquid crystal display device is provided which is capable of improving display quality of moving images. In the liquid crystal display device, every time a driving pulse voltage is generated by a backlight driving circuit in synchronization with a timing signal fed from a lighting timing control section and is applied to a backlight and a scanning signal is applied to each scanning electrode of a liquid crystal panel, the backlight is turned OFF during a period before completion of a response of each liquid crystal molecule to application of a display signal and is turned ON at time of the completion of the response. When displacement of each of the liquid crystal molecules is large and therefore the change in light transmittance is large, the backlight is turned OFF and, therefore, no change in luminance on a display screen occurs, as a result, contrast of images can be improved.

Abstract: A reflection electrode has an undulated shape and whose normal direction is distributed unevenly to a specific azimuth angle and whose reflection light intensity depends on said azimuth angle. Openings are formed in that area of the reflection electrode which has a tilt angle of 0 degree to 2 degrees and/or a tilt angle of 10 degrees or higher. The retardation of a liquid crystal layer is changed by making the liquid crystal molecular alignment mode different between the openings and the reflection electrode, so that the intensity of output light is increased in reflection mode as well as in transmission mode. The balance of colors displayed in transmission mode is determined by determining the area of the openings in pixels of each color, and the color temperature is set higher in transmission mode than in reflection mode. This provides a semi-transmission type liquid crystal display which has an excellent visibility in reflection mode as well as in transmission mode.
