Surface light source and display device having the same

A surface light source comprising:

• a body comprising:
• a first substrate on which an electrode is formed;
• a second substrate on which a transparent electrode is formed, the transparent electrode facing the electrode of the first substrate;
• and
• a sealing member interposed between the first and second substrates to seal the first and second substrates;
• an electron-emitting member disposed on the electrode to emit an electron toward the transparent electrode;
• a fluorescent layer disposed on the transparent electrode to convert the electron into visible light;
• and
• a supporting part integrally formed with the body to support the first substrate and the second substrate.

A surface light source comprising:

• a first substrate;
• a second substrate disposed over the first substrate, the second substrate including a light-emitting part having at least one ridge and grooves, wherein the grooves are adjacent to the ridge;
• an electrode disposed over the first substrate and corresponding to the light-emitting part, the electrode having substantially the same curvature as that of an inner surface of the light-emitting part;
• a transparent electrode formed on an inner surface of the second substrate corresponding to the first electrode;
• an electron-emitting member disposed on the first electrode to emit an electron;
• a conductive grid member having substantially the same curvature as that of the electron-emitting member to accelerate the electron emitted from the electron-emitting member;
• and
• a fluorescent layer disposed on an upper surface of the transparent electrode to convert the electron into visible light.

A display device comprising:

• a receiving container;
• a surface light source received in the receiving container, comprising:
• a body having first and second faces corresponding to each other;
• an electrode disposed on the first face;
• a transparent electrode disposed on the second face;
• an electron-emitting member disposed on the electrode to emit an electron toward the transparent electrode;
• a fluorescent layer disposed on the transparent electrode to convert the electron into visible light;
• and
• a supporting part integrally formed with the body to support the first and second faces;
• and
• a display panel received in the receiving container to display an image using the visible light.
