Patent ID: 8314919

Claim:
A liquid crystal display device, comprising: a liquid crystal panel having a liquid crystal layer between a pair of glass substrates; and a lighting device that supplies illumination light to said liquid crystal panel, wherein: at least one of said glass substrates has a colored portion including a nonbridging oxygen hole center in an area that can block light to a luminance point defect occurrence area in which a possible cause of luminance point defect is present, and said glass substrate in which said colored portion is formed contains at least one of sodium (Na) and potassium (K), wherein the colored portion is formed by a applying laser with a femtosecond order or shorter pulse width at an ultraviolet wavelength to said area of the glass substrate that can block light to the luminance point defect occurrence area, wherein the laser with a femtosecond order or shorter pulse width at an ultraviolet wavelength is applied to create a structural defect in a glass structure of said at least one of said glass substrates.
