Abstract

To provide a display device, a color filter, and an electronic apparatus, which can prevent the deterioration of resolution and display quality and can improve display characteristics. There is provided a display device comprising a plurality of dots in a unit pixel. The dots includes first to third dots having first to third peak wavelengths in the wavelength characteristics of emitted light, and a fourth dot having a fourth peak wavelength which is located between the first peak wavelength and the second peak wavelength, and has the fourth peak wavelength which is closer to the second peak wavelength than to the first peak wavelength, in the wavelength characteristics. The fourth dot is arranged not to be adjacent to the second dot, but is arranged to be adjacent to the first dot or the third dot.

Description

technical field [0001] The present invention relates to a display device, a color filter, and electronic equipment. Background technique [0002] Conventionally, various display forms have been proposed for display devices, for example, known CRT (cathode ray tube) displays, LCD (liquid crystal displays), organic electroluminescent devices (hereinafter referred to as organic EL devices), and plasma displays. . Such display devices all have the structure of three color points of R (red) / G (green) / B (blue) in the unit pixel, and various colors are realized by making the light intensity of the three color points different, and the Image display. [0003] However, in the natural world, there are wavelength regions of colors that cannot be displayed with only the three colors of R / G / B, and it is difficult to realize colors close to natural light. [0004] Therefore, in recent years, display devices capable of realizing colors closer to natural light have been proposed (for exa...
