Claims
- 1. A fluorescent display comprising:
- an envelope;
- an insulating anode substrate constituting a part of said envelope;
- light-permeable anode conductors formed on an inner `surface of said anode substrate;
- color filters made of a mixture of an insulating in organic pigment and a conductive material and formed on at least an upper surface of each of said anode conductors; and
- phosphor layers each formed on an upper surface of each of said color filters.
- 2. A fluorescent display device as set forth in claim 1, wherein:
- said anode conductors are arranged in strips;
- said color filters cover side surfaces of said anode conductors and are contiguous to an upper surface of said anode substrate; and
- said color filters are not in contact with each other.
- 3. A fluorescent display device as set forth in claim 2, wherein said color filters have an anisotropic conductivity wherein electrical conductivity is substantially only in a direction of the thickness of said color filters.
- 4. A fluorescent display device as set forth in claim 1, wherein:
- said anode conductors are arranged in strips;
- said color filters cover side surfaces of said anode conductors and color filters formed upon adjacent anode conductors are vertically overlapped on each other on a portion of said anode substrate between the adjacent anode conductors; and
- said color filters have an anisotropic conductivity with electrical conductivity substantially only in a direction of the thickness of said color filters to that there is substantially no electrical coupling between the adjacent anode conductors through said overlapped color filters.
- 5. A fluorescent display device comprising:
- an envelope including a light-permeable anode substrate;
- light-permeable anode conductors arranged in strips on an inner surface of said anode substrate and formed with openings;
- a plurality of color filters disposed in said openings of said anode conductors; and
- phosphor layers formed on said anode conductors, resulting in luminescence of said phosphor layers being observed through said openings of said anode conductors and said anode substrate.
- 6. A fluorescent display device as set forth in claim 5, wherein for each said anode conductor, said color filters disposed in said openings are discontinuous such that portions of said color filters in adjacent openings are not in contact with each other.
- 7. A fluorescent display device as set forth in claim 5, wherein said color filters further comprise through-holes, wherein said phosphor layers contact said anode conductors via said through-holes.
