Abstract
A color filter substrate includes: a transparent substrate; and a black matrix film, a color material film, and a repair color material film. which are formed on the substrate, wherein, in a display region, the repair color material film is formed on one of an upper surface and a lower surface of the black matrix film in at least a part overlapping the black matrix film in a plan view.
Claims20
A color filter substrate comprising:
- a transparent substrate;
- and
- a black matrix film, a color material film, and a repair color material film, which are formed on the substrate,
- wherein, in a display region, the repair color material film is formed on one of an upper surface and a lower surface of the black matrix film in at least a part overlapping the black matrix film in a plan view.
A manufacturing method of a color filter substrate, comprising:
- forming a black matrix film on a transparent substrate;
- forming a color material film;
- and
- forming a repair color material film in at least a part overlapping the black matrix film in a plan view in a display region.
A bright spot defect correction method of a display panel including a color filter substrate that includes:
- a transparent substrate;
- a black matrix film, a color material film, and a repair color material film, which are formed on the substrate;
- and the repair color material film is formed on one of an upper surface and a lower surface of the black matrix film in at least a part overlapping the black matrix film in a plan view in a display region, the bright spot defect correction method comprising:
- diffusing the black matrix film to a region of a bright-spot-defective pixel part by irradiating the black matrix film corresponding to the bright-spot-defective pixel part having a bright spot defect with fluidization laser light;
- and
- blackening the repair color material film to reduce transmittance by irradiating the repair color material film corresponding to the bright-spot-defective pixel part with repair color material film blackening laser light.
A bright spot defect correction method of a display panel including a color filter substrate that includes:
- a transparent substrate;
- a black matrix film, a color material film, and a repair color material film, which are formed on the substrate;
- and
- the repair color material film is formed on one of an upper surface and a lower surface of the black matrix film in at least a part overlapping the black matrix film in a plan view in a display region, the bright spot defect correction method comprising:
- blackening the repair color material film to reduce transmittance by irradiating the repair color material film corresponding to a bright-spot-defective pixel part with repair color material film blackening laser light;
- and
- diffusing the blackened repair color material film to a region of the bright-spot-defective pixel part.
