摘要： In a liquid crystal display device using a light emitting diode as a light source, even when a plurality of light emitting elements are provided, an inclined surface is formed on a light guide plate as a reflection surface, and a light is converged in the liquid-crystal-panel direction using the reflection surface. In a liquid crystal display device which includes a backlight for radiating a light toward a liquid crystal panel, LEDs are formed on the light guide plate which is mounted on the backlight as light emitting elements. The plurality of LEDs are arranged along a side surface of the light guide plate, and a first reflection surface and a second reflection surface are formed on a bottom surface of the light guide plate. The second reflection surface is arranged closer to the LEDs than the first reflection surface and an angle of the second reflection surface is set larger than an angle of the first reflection surface.

摘要： A color cathode ray tube includes an electron gun having cathode structures arrayed in line with a cup-shaped first grid electrode. Each of the cathode structures is fused and fixed to a cathode in an electrically insulated state by hermetic glass. A cathode support to which the cathode structures are fixed by glass is fixedly housed in the cup-shaped first grid electrode, and the first grid electrode and the cathode support are welded on an axis along which the cathode structures are arrayed. The cathode structures and the first grid electrode are welded on an inline axis so that the thermal deformation of the cathode support can be made uniform at the center portion and at side portions. Accordingly, at the start-up time of the color cathode ray tube, the cathode currents at the center portion and at the side portions can be equalized and a good color balance can be maintained on the screen.

摘要： A liquid crystal display device which can make the surface brightness of an edge-light-type backlight uniform is provided. The liquid crystal display device includes a liquid crystal display panel and a backlight which radiates light to the liquid crystal display panel. The backlight includes a light guide plate which is arranged on a back side of the liquid crystal display panel, a light source arranged on an outer peripheral portion of a first main surface of the light guide plate which faces the liquid crystal display panel in an opposed manner, and a reflection sheet which is arranged on a back side of the light guide plate as viewed from the liquid crystal display panel. The light guide plate is made of a transparent resin having a refractive index of 1.53 or less. On a surface of the light guide plate opposite to the first main surface, a second main surface which is substantially parallel to the first main surface and a plurality of inclined surfaces which are inclined at a preset angle with respect to the second main surface are formed. An angle of the inclined surface positioned near a position at which light from the light source is incident and an angle of the inclined surface positioned remote from the position at which the light from the light source from the light source is incident differ from each other.
