摘要： A backlight device includes light emitting diodes (LED's) and a plate-like light guide plate which guides light from the light emitting diodes to a liquid crystal panel. Grooves are disposed on the back of the light guide plate and the light emitting diodes are disposed in the grooves. The light emitting diodes disposed in the grooves are arranged so that light emission direction thereof is parallel with light emission plane of the light guide plate. First optical pattern is disposed on first side opposite to light emission plane of light emitting diodes and second optical pattern is disposed on second side opposite to the back of light emitting diodes. The optical patterns are formed into minute prism array or lens array, for example.

摘要： A cross section of each divided light guiding plate is formed in a wedge shape, a step is formed at a portion of each divided light guiding plate where LEDs are arranged, and holes used for accommodating the LEDs are formed at the step. A plated face is formed on a lower face of each LED, and is coupled to a wiring substrate through solder. Each LED includes a light-emitting face, a lower frame, and an upper frame. The height of the lower frame of each LED is larger than the height of the upper frame, so that a lower end of the light-emitting face of each LED can be always located higher than a lower end of the divided light guiding plate.

摘要： It is an object of the present invention to provide an image display apparatus which enables cost reduction while being free from electromagnetic interference problems.A power supply circuit comprises, on a single circuit board, an AC inlet to which a power cord is connected from an external AC power supply, a filter circuit to which an inductance element is connected to suppress leakage of electromagnetic waves to the outside of the image display apparatus, and a switch which switches on/off an AC output supplied from the filter circuit. The circuit board of the power supply circuit is entirely covered by electromagnetic shielding means to shield electromagnetic waves. The electromagnetic shielding means is composed of, for example, a first shielding section which surrounds the lateral side of the circuit board and a second shielding section which covers the upper side of the circuit board. The second shielding section is formed of a part of the flat section of a rear cover of the image display apparatus.

摘要： A back substrate has a plurality of electron emission elements. A display substrate comprises an optically transparent substrate disposed opposite to the back substrate; an accelerating electrode formed on the inner face of the optically transparent substrate for accelerating electron beams emitted from the electron emission elements; and luminescent materials excited by the electron beams to emit light toward the outer face of the optically transparent substrate. A frame member supports the back substrate and display substrate on their peripheries. A vacuum chamber is defined by the back substrate, display substrate, and frame member. A conductor electrically connected to the accelerating electrode is drawn out to the outside of the vacuum chamber. A high voltage connector for supplying an accelerating voltage to the conductor is removably connected to the conductor.
