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, whereinthe 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, andthe 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.
