Patent ID: 7839063

Claim:
A display panel including a color filter, a color filter protective film, a phosphor layer, and an anode electrode formed in that order over a substrate in a plurality of fluorescent regions, and including a plurality of electron sources that emit electrons so as to penetrate respective anode electrodes and collide with respective fluorescent regions to allow the fluorescent regions to emit light, wherein the color filter protective layer protects the color filter from being oxidized, wherein a light-absorbing black matrix is formed so as to separate adjacent color filters by said black matrix; and wherein the color filter protective film is comprised of at least one material selected from the group consisting of aluminum nitride, chromium nitride, chromium oxide, silicon nitride, and silicon oxide nitride; and further wherein partitions are formed over the substrate in regions between the color filters and the color filter protective film is formed over the color filters and over the partitions to thereby seal and protect the color filters, the fluorescent regions being formed directly on portions of the color filter protective film at locations corresponding to the color filters, the color filter protective film being the only layer between the color filters and the fluorescent regions.
