The mathematical model of color representation of LCD-panels is researched. The mathematical expressions describing the shifts of chromaticity coordinates for different samples of LCD panels by various manufacturers and by one the same manufacturer are presented. The mathematical expressions for calculation of the profile coefficients for any LCD-panel through the given values of coordinates of the chromatic triangle vertexes and white color point are presented. The results, obtained by mathematical simulation technique, are presented, demonstrating a possible use of two-dimensional normal distribution to describe chromaticity coordinates, which are random because of manufacturer's technological variations.
