Abstract
A display device substrate includes a transparent substrate, a frame member disposed on the transparent substrate and formed in a frame region surrounding a display region, a first transparent resin layer formed on the transparent substrate having the frame member formed thereon, a black matrix formed on the first transparent resin layer such that the display region is divided into plural openings in a matrix form, and a second transparent resin layer formed on the first transparent resin layer on which the black matrix is formed. The frame member includes carbon as a major colorant and has a light shielding property, and the black matrix includes at least one organic pigment as a major colorant.
Claims14
A display device substrate, comprising:
- a transparent substrate;
- a frame member disposed on the transparent substrate and formed in a frame region surrounding a display region;
- a first transparent resin layer formed on the transparent substrate having the frame member formed thereon;
- a black matrix formed on the first transparent resin layer such that the display region is divided into a plurality of openings in a matrix form;
- and
- a second transparent resin layer formed on the first transparent resin layer on which the black matrix is formed,
- wherein the frame member comprises carbon as a major colorant and has a light shielding property, and the black matrix comprises at least one organic pigment as a major colorant.
A display device, comprising:
- a display device substrate having a display region and a frame region surrounding the display region;
- a liquid crystal layer;
- an array substrate that faces the display device via the liquid crystal layer, the array substrate including a plurality of metal wirings and a plurality of active elements,
- wherein the active elements include a liquid crystal drive element and a light receiving element,
- the metal wirings comprise a metal on a surface thereof, which reflects a light having a wavelength in a sensitivity region of the light receiving element,
- the display device substrate includes
- a transparent substrate,
- a color filter formed on the transparent substrate and including a red filter, a green filter and a blue filter,
- a first transparent resin layer formed on the color filter,
- a black matrix formed on the first transparent resin layer such that the display region is divided into a plurality of openings in a matrix form, the black matrix including at least one organic pigment as a major colorant,
- a second transparent resin layer formed on the first transparent resin layer on which the black matrix is formed, and
- a backlight unit disposed near a back surface of the array substrate which is opposite to a side where the liquid crystal layer is formed, the backlight unit being configured to emit a visible light and a light having a wavelength in the sensitivity region of the light receiving element.
