Abstract
There is provided an image display device which can prevent a charge-up occurring on the surface of an insulation substrate with a simple constitution even if any antistatic film is not provided. In the image display device which includes an electron-emitting device on an insulation layer on the substrate, there is provided a conductive layer which is an orthogonal projection region of an anode electrode and includes a predetermined metal kind directly below an exposed surface of the insulation layer.
Claims7
An image display device comprising:
- a light emission layer, and an anode electrode provided on the light emission layer;
- an insulation member, and an electron-emitting device provided on the insulation member;
- and
- a conductive layer,
- wherein the anode electrode is opposed to the electron-emitting device, and electrons emitted from the electron-emitting device irradiate the anode electrode and the light emission layer,
- wherein the insulation member has an exposed surface opposite to the anode electrode, and at least a part of the exposed surface is positioned between the conductive layer and the anode electrode,
- wherein the conductive layer includes at least two kinds of metals, respectively selected from at least two groups among a first group consisting of metals belonging to the third period of the periodic table, a second group consisting of metals belonging to the fourth period of the periodic table, and a third group consisting of metals belonging to the fifth and sixth periods of the periodic table,
- wherein the anode electrode includes A1,
- wherein the light emission layer includes a fluorescent member mainly containing ZnS and a fluorescent member mainly containing Y2O2S, and
- wherein the conductive layer includes A1, includes at least one kind of metal selected from among Ni, Fe and Ti, and includes at least one kind of metal selected from Pt and Ta.
