Disclosed is a backlight device used for a color liquid crystal display (LCD) apparatus. The red light, green light and blue light, generated by a light source, made up by a red light emitting diode (21R), a green light emitting diode (21G) and a blue light emitting diode (21B), respectively, are mixed together to generate white light. The red light has a half-value width hwr such that 15 nm≦hwr≦30 nm, and the green light has a half-value width hwg such that 25 nm≦hwg≦50 nm. The blue light has a half-value width hwb such that 15 nm≦hwb≦30 nm. The white light illuminates a transmissive color liquid crystal display panel (10) from its back side. The transmissive color liquid crystal display panel includes a color filter (19) made up by a tristimulus filter for wavelength-selecting and transmitting red light, green light and blue light.

The present invention relates to a solid-state imaging element and electronic information equipment. In order to receive correct signals in the light receiving part, color mixing is suppressed more effectively. A grid-shaped light-shielding wall (8) is set in the pixel boundary part of the boundary part of the color filter (5a, 5b), so that the height between the microlens (7) and the semiconductor substrate (2) is reduced, and then the light-shielding wall (8) (or reflective wall) height is set to 3 / 4 or more of the thickness of the color filter ( 5 a , 5 b ). In addition, the color filters ( 5 a , 5 b ) are formed to be embedded in the grid-shaped light-shielding walls ( 8 ) (or reflecting walls). Accordingly, color mixing is more effectively suppressed in order to receive accurate signals in the light receiving unit.

An aqueous ink comprises water, a water-insoluble coloring material, and plurality of water-soluble organic solvents and the plurality of water-soluble organic solvents including a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material. The ratio of the content of the poor medium and the content of the good medium is in a specific range. A water-soluble organic solvent showing the maximum Ka value out of respective Ka values of the plurality of water-soluble organic solvents is the poor medium. When the aqueous ink is in contact with a specific reaction liquid, the dissolution state or dispersed state of the water-insoluble coloring material in the ink is made unstable. As a result, an image which has a sufficiently large area factor even with a small amount of ink droplets and is excellent in image density, bleeding resistance, and fixability can be obtained. In addition, the aqueous ink is excellent in storage stability.
