Problems solved by technology

Arcing causes damage to the internal structure of the device and results in defective devices
[0006] Therefore, the conventional light-emitting device has the disadvantage that the voltage applied to the anode electrode cannot be sufficiently increased to achieve high brightness due to arcing.

Embodiment Construction

[0022] 1 and 2, the light emitting device 10 of the present example embodiment includes first and second substrates 12 and 14, which face each other in parallel and are spaced apart from each other by a certain distance or gap. The interval between the two substrates may be predetermined. Sealing members 16 are provided at the edges of the first and second substrates 12 and 14 to seal them together and thus form a vacuum container. The interior of the vacuum container is evacuated to a vacuum, and the vacuum is maintained at about 10 -6 Torr pressure.

[0023] Within the vacuum container formed by the sealing member 16, the first and second substrates 12 and 14 are each divided into an active region for emitting visible light and an inactive region surrounding the active region. Electron emission units 18 for emitting electrons are provided on the active area of ​​the inner surface of the first substrate 12 , and light emitting units 20 for emitting visible light are provide...

Abstract

The present invention provides a light emission device and a display device using the light emission device as a light source. The light emission device includes a vacuum vessel having first and second substrates and a sealing member, an electron emission unit provided on an inner surface of the first substrate and having driving electrodes and electron emission regions, a light emission unit provided on an inner surface of the second substrate, a plurality of spacers located between the first and second substrates, and a resistive layer formed on the first substrate and coupled to at least one of the driving electrodes. The resistive layer surrounds a circumference of the spacer.

Description

technical field [0001] The present invention relates to a light-emitting device and a display device, in particular to a light-emitting device capable of enhancing brightness and a display device using the light-emitting device as a light source. Background technique [0002] A conventional light-emitting device includes a rear substrate provided with an electron emission region and a front substrate provided with a phosphor layer and an anode electrode. Electrons emitted from the electron emission regions excite the phosphor layer to emit visible light from the phosphor layer. [0003] Sealing members are provided at the edges of the front and rear substrates to seal them together, and thus form a vacuum vessel, the inner space of which is evacuated. A spacer is provided between the front and rear substrates to withstand the pressure applied to the vacuum vessel. [0004] When a light emitting device is used as a light source for a display device, it is desirable to achie...
