Patent ID: 7800294

Claim:
A light emission device comprising: first and second substrates facing each other and forming a space therebetween; an electron emission unit located on the first substrate; and a light emission unit located on the second substrate, wherein the electron emission unit and the light emission unit face each other; wherein the light emission unit includes: a transparent anode electrode formed on the second substrate; a phosphor layer formed on the anode electrode; and at least one sub-electrode located on the anode electrode, wherein the at least one sub-electrode has a resistance lower than that of the anode electrode, wherein the phosphor layer includes a plurality of sections spaced apart from each other, wherein the at least one sub-electrode comprises a plurality of first and second sub-electrodes, wherein the plurality of second sub-electrodes are formed between the sections of the phosphor layer, and wherein at least one second sub-electrode has a width greater than that of the first sub-electrodes.
