摘要： To prevent, in a backlight where light emitting diodes are arranged on a side surface of a light guide plate, light leakage from a reflection sheet and reduce non-uniformity of emission light from the backlight. In a liquid crystal display device that includes a backlight that irradiates a liquid crystal panel with light, LEDs are disposed as light emitting elements on a light guide plate that is disposed in the backlight, a reflection sheet that comprises a multilayer film is disposed on a bottom surface of the light guide plate, projections are disposed by sandblasting on the bottom surface of the light guide plate in the vicinity of the LEDs, and tight adhesion between the reflection sheet and the light guide plate is prevented. In the vicinity of the LEDs, in order to counter light non-uniformity, reflecting grooves are not disposed and it is a mirror surface, but tight adhesion can be prevented by disposing the projections.

The second focusing electrode includes a couple of horizontal plate electrodes arranged in such a manner as to hold the electron beams along the direction perpendicular to the direction of arrangement thereof after being passed through passage apertures and extending in opposed relationship with the perpendicular plate electrodes and rim electrodes along tht electron gun axis. The resolution of the peripheral parts of the display surface of the picture tube is thus improved and the assembly of the electron gun thereof is facilitated.
