Liquid crystal display device
First Claim
1. A liquid crystal display device including a liquid crystal display panel which a pair of substrate, a back light and a controller, wherein the liquid crystal display panel includes;
- a test pixel for detection which has the same constitution as respective pixels constituting a liquid crystal display part of the liquid crystal display panel is formed on a region other than the liquid crystal display part, a black matrix which are formed on one of the substrate, a light through hole which are formed on the black matrix, light from the backlight through the test pixel and the light through hole, a light detector which detects light from the light through hole, and the controller which adjusts the intensity of the light from the backlight in response to a signal from the light detector.

Abstract
In a liquid crystal display device including a liquid crystal display panel and a backlight, the present invention provides a detection-use pixel having the same constitution as respective pixels constituting a liquid crystal display part in the liquid crystal display panel and being formed on a region other than the liquid crystal display part, a light detector detecting light from the backlight through the detection-use pixel, and a controller adjusting the intensity of the light from the backlight in response to a signal from the light detector to adjust the change of the characteristics and chromaticity in the liquid crystal display panel properly.
