ABSTRACT:
A liquid crystal display device10in accordance with the present invention includes a liquid crystal11and a lighting device12, the liquid crystal panel11having a liquid crystal layer50provided between a pair of glass substrates31, 41, the lighting device12supplying illumination light to the liquid crystal panel11. The liquid crystal display device10is characterized in that a metal-halide containing region60is formed in a position in one of the pair of glass substrates31, 41. The metal-halide containing region60contains a crystal of metal halide which exhibits photochromism in the light supplied from the lighting device12. The position is capable of blocking light toward a luminance point defect occurrence portion X that becomes a cause of a luminance point defect. The one of the pair of glass substrates31, 41is disposed on the lighting device12side.
