Abstract

In a pixel defect correct method, a refractive index varying area which is different in refractive index from the surroundings thereof in a plane parallel to an image display face is equipped on a defective pixel of the image display face and thereby light is scattered from the refractive index varying area, and the defective pixels of the image display are made inconspicuous. In a color mura correcting method, a color mura film is equipped to an image display portion of an image display device, the complementary color of the color mura is generated in the color mura correcting film in connection with the color mura of the display image, and thereby the color mura of the display device is made inconspicuous.

Claims

1. A pixel defect correcting method for image display, the method comprising:

equipping a refractive index varying area, which is different in refractive index from the surroundings thereof in a plane parallel to an image display face, on a defective pixel on the image display face.

4. The pixel defect correcting method for image display according to claim 1, wherein the refractive index is varied by irradiating a laser beam to thereby equip the refractive index varying area.

2. A pixel defect correcting method for image display, the method comprising:

equipping a pixel defect correcting film on an image display face; and

equipping a refractive index varying area, which is different in refractive index from the surroundings thereof in a plane parallel to the image display face, to a portion of the pixel defect correcting film which is located above a defective pixel.

5. The pixel defect correcting method for image display according to claim 2, wherein the refractive index is varied by irradiating a laser beam to thereby equip the refractive index varying area.

3. A pixel defect correcting method for image display, the method comprising:

attaching an image defect correcting film having a refractive index varying area, which is different in refractive index from the surroundings thereof in a plane parallel to a film face, onto an image display face so that the refractive index varying area is located above a defective pixel.

6. The pixel defect correcting method for image display according to claim 3, wherein the refractive index is varied by irradiating a laser beam to thereby equip the refractive index varying area.

7. An image display device, wherein a defective pixel of image display is substantially corrected by a refractive index varying area on an image display face which is different in refractive index from the surroundings thereof in a plane parallel to the image display face.

8. An image display device comprising:

a refractive index varying area which is different in refractive index from the surroundings thereof in a plane parallel to an image display face, the refractive index varying area being equipped above a defective pixel of the image display face.

9. An image display device comprising:

a pixel defect correcting film having a refractive index varying area, which is different in refractive index from the surroundings thereof in a plane parallel to an image display face, on the image display face, the refractive index varying area being located above a defective pixel of the image display face.

10. The image display device according to claim 9, wherein the pixel defect correcting film comprises photochromic material.

11. A color mura correcting method comprising:

equipping a color mura correcting film is equipped to an image display portion of an image display; and

correcting a color mura of a display image by the color mura correcting film,

wherein the complementary color of the color mura is generated in the color mura correcting film in accordance with the color mura of the display image.

12. The color mura correcting method according to claim 11, comprising:

equipping the color mura film with a refractive index varying structure which is periodically varied in refractive index and generates the complementary color of the color mura of the display image through light interference, whereby the complementary color of the color mura of the display image is generated in the color mura correcting film.

13. The color mura correcting method according to claim 12, wherein the refractive index varying structure is equipped by irradiation of a laser beam.

14. An image display device comprising:

a color mura correcting film for generating a complementary color of a color mura of a display image in accordance with the color mura, the color mura correcting film being equipped to an image display portion.

15. The image display device according to claim 14, wherein the color mura correcting film comprises a refractive index varying structure which is periodically varied in refractive index and generates the complementary color of the color mura of the display image through light interference.
