摘要:
A light guide panel and liquid crystal display device including a liquid crystal cell array, a light guide panel or plate disposed on a rear surface of the liquid crystal cell array, and a light source disposed at a lateral side of the light guide panel or plate. The light guide panel or plate has a light incident surface on which light rays emitted from the light source are incident, a light-transmissive surface through which the incident light rays exit the light guide panel or plate toward the liquid crystal cell array, and a plurality of reflecting slant portions for directing the incident light rays toward the light-transmissive surface, wherein the reflecting slant portions are constituted by convexes or concaves which are substantially rectangular in plan view and substantially trapezoidal in sectional view.

A liquid crystal display apparatus having a light conductor plate, a liquid crystal cell arranged on a front surface side of the light conductor plate, and a light source arranged on a side surface of the light conductor plate so as to light the liquid crystal cell from a back surface side thereof. The light conductor plate has an incident surface for a light from the light source, a light emitting surface for emitting the input light to the liquid crystal cell, and a plurality of dots constituted by small projecting portions or small recess portions for changing a moving direction of the light from the incidence surface toward a direction of the light emitting surface. The dots are formed in at least one of the light emitting surface and a surface of the light conductor plate opposite to the light emitting surface and have a particular configuration.

A method of manufacturing a light conductor plate for a liquid crystal display apparatus forming a photo resist on a stamper original plate, arranging a photo mask having a flat surface shape pattern or an inverted pattern of a dot constituted by a small projecting portion or a small recess portion on a base plate and developing after irradiating an ultraviolet ray from an upper portion of a mask so as to form a pattern for forming the small projecting portion or the small recess portion on the stamper original plate, making the pattern in a mask and etching the stamper original plate so as to form a plastic forming metal stamper, and a plastic molding using the stamper.
摘要:
The present invention provides a liquid crystal display apparatus having a high brightness and a less number of constituent parts. By forming a plurality of dots each constituted by a small projecting portion or a small recess portion for changing a light at a predetermined angle from an incident surface of a light conductor plate toward a direction of a transmitting surface and properly controlling an angle of incline of a cross section, it is possible to irradiate an illuminating light having a suitable angle distribution from a light emitting surface toward a display element, thereby improving a brightness of the liquid crystal display apparatus.
摘要:
A liquid crystal display having a liquid crystal display panel having a plurality of liquid crystal cells, and a back light that irradiates the liquid crystal display panel with irradiation light. The back light includes a light source, and a light guide plate having one side arranged adjacent the light source and having a planar surface with a plurality of small concaves. The planar surface is almost parallel to a liquid crystal cell face, and a plane shape of the small concaves is almost rectangular.

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.
