Abstract
A display device includes a cathode plate having a minute field emission cathode to emit electrons into an area defining a pixel, a spacer support member, and an anode plate placed between the cathode plate and the spacer support member, the anode plate having a fluorescent layer in the area defining the pixel, wherein the spacer support member is provided with a plurality of pole members for contacting the cathode plate and supporting the cathode plate against atmospheric pressure, the pole members extending vertically toward the cathode plate from a surface of the spacer support member and passing through a plurality of through-holes provided on the anode plate without contacting the anode plate.
Claims4
A display device comprising:
- a cathode plate having a minute field emission cathode to emit electrons into an area defining a pixel;
- an anode plate having a fluorescent layer in the area defining the pixel;
- and
- a single spacer support member in a lattice form;
- wherein the single spacer support member is placed in a space defined by the cathode plate and the anode plate, and the single spacer support member has a plurality of through-holes opening in a direction from the cathode plate to the anode plate, and the through-holes correspond to the areas defining pixels.
