COLOR LIQUID CRYSTAL DISPLAY UNIT

摘要

A high-color-purity color liquid crystal display unit having an NTSC ratio of at least 80%. A color liquid crystal display unit comprising, all combined together, an optical shutter using a liquid crystal (7), color filters (9) having color elements of at least three colors, red, green and blue corresponding to the optical shutter, and translucent lighting backlights (1, 2). When the spectral transmittance of the color filters (9) at a wavelength lambdan (wavelength of every 5 nm in a visible light region of 380-780 nm) nm by a green pixel is T<G>(lambdan), and the relative luminous intensity standardized by a total luminous intensity at a wavelength lambdan nm from backlights is I (lambdan), they satisfy the conditions in the followings (1)-(3). (1) At one of wavelengths of 500 nm < LAMBDAn < 530 NM, I (LAMBDAn) x T<G>(lambdan) > 0.01 (2) In a wavelength region of 610 nm < LAMBDAn < 650 NM, I (LAMBDAn) x T<G>(lambdan) < 0.0001 (3) In a wavelength region of 400 nm < LAMBDAn < 450 NM, I (LAMBDAn) x T<G>(lambdan) < 0.0001
