Abstract

A flat panel display apparatus is disclosed. In one embodiment, the apparatus includes a panel configured to display an image; a glass window covering the panel; and a polarizing film attached on a surface of the glass window, wherein the polarizing film is configured to prevent the scatter of broken pieces when the glass window breaks and also prevent reflection of an external light.

a touch screen formed between the panel and the polarizing film, wherein the polarizing film and the touch screen contact each other via an adhesive,

wherein the touch screen comprises;

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and

an insulating material interposed between the substrates and fully covering top and side surfaces of each of the first and second electrode patterns.

2. The display of claim 1, wherein the surface of the glass window faces the panel.

3. The display of claim 1, wherein the touch screen comprises:

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and

an insulating material interposed between the substrates and covering the electrode patterns.

4. The display of claim 1, wherein the glass window is formed over the polarizing film.

5. The display of claim 4, further comprising an adhesive formed between the glass window and the polarizing film.

11. The display of claim 1, wherein the panel is an organic light emitting panel or a liquid crystal panel.

12. The display of claim 1, wherein the polarizing film is formed at least partially of a non-glass material.

22. The display of claim 1, wherein the first electrode pattern includes a plurality of first electrodes, wherein the second electrode pattern includes a plurality of second electrodes respectively facing the first electrodes, and wherein the insulating material fully covers top and side surfaces of each and every one of the first and second electrodes.

6. A flat panel display comprising:

a panel configured to display an image;

a glass window covering the panel;

and

a polarizing film attached on a surface of the glass window, wherein the polarizing film is configured to prevent the scatter of broken pieces when the glass window breaks and also prevent reflection of an external light, wherein the surface of the glass window does not face the panel; and

a touch screen formed between the panel and the glass window,

wherein the touch screen comprises;

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and

an insulating material interposed between the substrates and fully covering top and side surfaces of each of the first and second electrode patterns.

7. The display of claim 6, further comprising a touch screen formed between the panel and the glass window.

8. The display of claim 7, wherein the touch screen comprises:

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and

an insulating material interposed between the substrates and covering the electrode patterns.

9. The display of claim 7 6, wherein the polarizing film is formed over the glass window.

10. The display of claim 9, further comprising an adhesive formed between the polarizing film and the glass window.

13. A flat panel display comprising:

a panel configured to display an image;

a glass window configured to cover the panel, wherein the glass window has first and second surfaces opposing each other, wherein the first surface is closer to the panel than the second surface;

a polarizing film formed between the first surface of the glass window and the panel, wherein the polarizing film is closer to the panel than the glass window, and wherein the polarizing film is formed at least partially of a non-glass material which is configured to prevent the scatter of broken pieces when the glass window breaks; and

a touch screen formed between the panel and the polarizing film, wherein the polarizing film and the touch screen contact each other via an adhesive,

wherein the touch screen comprises;

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and

an insulating material interposed between the substrates and fully covering top and side surfaces of each of the first and second electrode patterns.

14. The display of claim 13, wherein the glass window and the polarizing film contact each other via an adhesive.

15. The display of claim 13, wherein the touch screen and the panel contact each other via an adhesive.

16. A flat panel display comprising:

a panel configured to display an image;

a glass window configured to cover the panel;

a touch screen foil led between the panel and the glass window; and

a polarizing film having first and second surfaces opposing each other, wherein the first surface is closer to the panel than the second surface, and wherein the glass window is formed between the first surface of the polarizing film and the touch screen,

wherein the touch screen comprises;

first and second substrates facing each other;

first and second electrode patterns formed on the first and second substrates, respectively, wherein the first and second electrode patterns face each other; and
