摘要： A light guide plate which can achieve improvement of back-lighting or front-lighting luminance without increase of luminance of a light source, and a liquid crystal display device using such a light guide plate. A large number of concave small dots are formed in a surface of the light guide plate opposite to a light emitting surface of the light guide plate which emits light to a liquid crystal cell array so that light incident on the light guide plate from the light source is reflected at the concave small dots in the direction toward the light emitting surface of the light guide plate. Each of the concave small dots is shaped like a triangle with a sectional inclination angle of from 50 to 60° in sectional view and shaped like an approximate rectangle or square in plan view in the direction perpendicular to a surface of the light guide plate and disposed so that a long side of the approximate rectangle or a side of the approximate square is approximately parallel with the longitudinal direction of the light source.

摘要： A backlighting unit for a liquid crystal display device includes a light guide plate and an optical member, one of which is provided with a random dot disposition pattern so that luminance of the backlighting unit is uniform over the surface thereof while suppressing moire and dot visibility. A dot pattern of concave or convex portions effective for reflection, scattering, refraction, diffraction, absorption, transmission, polarization or deflection of light rays or portions exhibiting different optical characteristics or portions imparted with optical activity is formed in a surface of the light guide plate or optical member. The dot pattern is determined to exhibit randomness by using random numbers so as to meet predetermined conditions concerning radial distribution function. In the random dot pattern superposed onto a regular color filter pattern, occurrence of moire is suppressed. A dot overlap suppressing processing is performed for preventing inter-dot overlap and abnormal proximity between the adjacent dots.
