Abstract

A flat panel display device has a conductive layer formed between a substrate and a polarization plate to prevent static electricity from appearing between the substrate and the polarization plate, thereby improving screen display quality. The flat panel display device includes: a flat display panel including a substrate having an image display unit, a display element arranged on the image display unit of the substrate, and a sealing unit for sealing the display element; a polarization member arranged on at least one of the substrate and the sealing unit; and a shielding member arranged at a portion that does not correspond to the image display unit of the substrate in order to prevent the appearance of static electricity between the substrate and the polarization member.

Claims (22)

1. A flat panel display device, comprising:

a flat display panel including a substrate having an image display unit;

a display element arranged on the image display unit of the substrate, and including a sealing unit for sealing the display element;

a polarization member arranged on at least one of the substrate and the sealing unit; and

a shielding member disposed between the substrate and the polarization member for preventing an appearance of static electricity between the substrate and the polarization member;

wherein the shielding member is formed in a closed loop shape.

2. The flat panel display device of claim 1 , wherein the shielding member includes a shielding film arranged at an outline of the polarization member that does not correspond to the image display unit.

3. The flat panel display device of claim 1 , wherein the shielding member is arranged at one of the substrate and the sealing unit in which the polarization member is arranged, and includes a shielding film arranged at an outline of the polarization member that does not correspond to the image display unit.

4. The flat panel display device of claim 1 , wherein the shielding member includes a conductive film comprising one of a conductive metallic film and a conductive nonmetallic film.

5. The flat panel display device of claim 1 , wherein the shielding member includes a conductive film comprising one of a transparent conductive film and an opaque conductive film.

6. The flat panel display device of claim 1 , wherein the flat display panel is an electroluminescence (EL) display panel.

7. A flat panel display device, comprising:

a flat panel display panel including a substrate having an image display unit,

a display element arranged on the image display unit of the substrate, and including a sealing unit for sealing the display element;

a polarization member arranged on at least one of the substrate and the sealing unit; and

a shielding member disposed between the substrate and the polarization member for preventing an appearance of static electricity between the substrate and the polarization member;

wherein the shielding member is formed in a mesh shape.

8. The flat panel display device of claim 7 , wherein the flat display panel is an electroluminescence (EL) display panel.

9. The flat panel display device of claim 7 , wherein the shielding member includes a shielding film arranged at a portion of the polarization member that corresponds to the image display unit.

10. The flat panel display device of claim 7 , wherein the shielding member is arranged at one of the substrate and the sealing unit in which the polarization member is arranged, and includes a shielding film arranged at a portion of the polarization member that corresponds to the image display unit.

11. The flat panel display device of claim 7 , wherein the shielding member includes a conductive film comprising one of a conductive metallic film and a conductive nonmetallic film.

12. The flat panel display device of claim 7 , wherein the shielding member includes a transparent conductive film.
