摘要： A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).

摘要： A liquid crystal display unit is characterized by comprising a liquid crystal display panel, a back-light instrument for outputting light to the liquid crystal display panel, and a scattering-anisotropic optical instrument disposed on that side of the liquid crystal display panel which is opposite to the back-light instrument. The scattering-anisotropic optical instrument is so formed that the scattering intensity of light vertically entering the display screen of the liquid crystal panel is maximized. Therefore, the scattering-anisotropic optical instrument can scatter light vertically entering the display screen of the liquid crystal panel to allow a viewer to view a display screen from a wide range of viewing angles. In addition, because the unit does not scatter light entering obliquely, rather than vertically, a display screen but lets the light pass as it is, whitish appearance as is seen in an oblique-direction observation can be prevented. Therefore, whitish appearance can be prevented even if the back-light instrument does not output perfectly parallel light.
摘要翻译：液晶显示单元的特征在于包括液晶显示面板，用于向液晶显示面板输出光的背光装置，以及配置在与液晶显示面板相对的液晶显示面板的该侧的散射各向异性光学仪器到背光仪器。散射各向异性光学仪器被形成为使得垂直进入液晶面板的显示屏的光的散射强度最大化。因此，散射各向异性光学仪器可以使垂直进入液晶面板的显示屏的光散射，以使得观看者能从宽范围的视角观看显示屏。此外，由于该单元不散射倾斜地进入的光，而不是垂直地进入显示屏幕，而是让光线原样通过，因此可以防止沿倾斜方向观察发现的白色外观。因此，即使背光装置不能完全平行地输出光，也可以防止发白的外观。

摘要： A vapor growth apparatus and a vapor growth method is capable of growing a compound semiconductor layer having an evenness and an interfacial sharpness in units of atomic layers with a good productivity. A growth chamber has a cylindrical portion and an end plate which closes an upstream end of the cylindrical portion. The end plate is provided with a cation gas material supply inlet and an anion material gas supply inlet, while an exhaust device is provided on the downstream side of the cylindrical portion. A substrate holder having a substrate support surface is provided in the cylinder portion. A gas separating member separates flow paths of material gases from each other, thereby forming on the substrate support surface a plurality of material gas supply areas to which the material gases are independently supplied. A drive device rotates the substrate holder with a substrate set on the substrate support surface thereof around the center line of the cylindrical portion. Then a cation material and an anion material gas are alternately supplied to the surface of the substrate.

摘要： A liquid crystal data calculation section forms, on the basis of input image data, liquid crystal data to display an image on a liquid crystal panel. In at least one example embodiment, an LED data calculation section forms, on the basis of the input image data, LED data for adjusting an amount of light of an LED backlight. An LED control section controls an amount of an output current of an LED power source on the basis of the LED data, and includes a protection function of limiting the amount of the output current so that the amount of the output current does not exceed a predetermined upper limit. In a case where the amount of the output current of the LED power source is reduced to the upper limit by the LED control section, a liquid crystal transmittance correction section corrects the liquid crystal data and increases transmittance so as to compensate reduction in luminance of the backlight.
