摘要： A color filter includes a red filter segment, a green filter segment and a blue filter segment, on a substrate, wherein when a pseudo-white LED is used, an area of a triangle defined by three chromaticity points of the red, green and blue filter segments expressed as (xR, yR), (xG, yG) and (xB, yB) on the x-y chromaticity diagram occupies 72% or more of an area standard triangle defined by defined by 3 points of red (0.67, 0.33), green (0.21, 0.71) and blue (0.14, 0.08), and the color filter has a color temperature of 6000K or more. Each of the red, green and blue filter segments has a thickness of 3.3 μm or less. A liquid crystal display device includes such color filter and the pseudo-white LED.

摘要： PROBLEM TO BE SOLVED: To solve the problem of retardation in a color filter in which color filter layers of red, green and blue pixel patterns are different from one another in retardation, the red layer shows a positive or negative retardation, the blue layer shows a positive retardation and the green layer shows a negative retardation. SOLUTION: In a color filter in which at least red pixels, green pixels and blue pixels are arranged on a transparent substrate, the green pixels are formed from a cured product of a colored composition containing a retardation regulator, so that the retardation difference between different color pixels is reduced and a color filter having good display properties can be obtained.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that the retardation of a color filter (CF) fabricated on a transparent substrate is wavy because of influences of multiple interferences in the CF with respect to wavelengths, and thereby, the retardation is not enough as a basic data for calculating a three-dimensional refractive index at each wavelength or the wavelength dependence. SOLUTION: A transparent substrate having a reflectance as low as possible from the CF is used, on which linearly polarized light is allowed to be incident perpendicular to the substrate to obtain the optical axis within the plane of the thin film (a layer in the CF); monochromatic polarized light propagating within a plane including the optical axis and perpendicular to the CF is allowed to be incident to the thin film at a plurality, at least three, of incident angles ϕi, to obtain the corresponding retardation R(ϕi); a calculation formula R(ϕi;n x , n y , n z , β) for the three-dimensional refractive index is determined; and the three-dimensional refractive index of the CF is determined by obtaining nx, ny, nz and β by using the above retardation R (ϕi) and the calculation formula R so as to minimize (R(ϕi)-R(ϕi;n x , n y , n z , β)) 2 . The CF substrate has a CF layer having a retardation controlled to -20 to 50 nm by using the above value. COPYRIGHT: (C)2010,JPO&INPIT
