Abstract

A display device has a display panel having a first substrate for displaying an image that is observed from a front surface of the first substrate. A translucent substrate covers the display panel from the front surface of the first substrate. The translucent substrate has a rear surface and a first light shielding portion on a periphery of the rear surface. A photo-curable translucent adhesive integrally bonds a front surface of the first substrate and the rear surface of the translucent substrate to each other. A first light reflecting portion is formed on the first light shielding portion of the translucent substrate. A second light reflecting portion is formed on a surface of the first substrate so as to oppose the first light reflecting portion through the photo-curable translucent adhesive.

Claims (25)

1. A display device, comprising:

a display panel having a first substrate for displaying an image that is observed from a front surface of the first substrate;

a translucent substrate covering the display panel from the front surface of the first substrate, the translucent substrate having a rear surface and a first light shielding portion on a periphery of the rear surface;

a photo-curable translucent adhesive for integrally bonding a front surface of the first substrate and the rear surface of the translucent substrate to each other;

a first light reflecting portion formed on the first light shielding portion of the translucent substrate; and

a second light reflecting portion formed on a surface of the first substrate so as to oppose the first light reflecting portion through the photo-curable translucent adhesive.

2. A display device according to claim 1 ; further comprising:

a second light shielding portion disposed on a periphery of the display panel;

a second substrate forming the display panel with the first substrate, the second light reflecting portion being formed on a rear surface of the first substrate;

a liquid crystal layer sandwiched between the first substrate and the second substrate; and

a polarizing plate attached on the front surface of the first substrate.

3. A display device according to claim 2 ; wherein the first substrate comprises a color filter substrate, a black matrix being formed on the rear surface of the color filter substrate; and wherein the second light reflecting portion is formed between the black matrix and the color filter substrate.

4. A display device according to claim 1 ; wherein the first substrate has color filters and a black matrix on a rear surface of the first substrate, a second light shielding portion being formed between the black matrix and the first substrate.

5. A display device according to claim 1 ; wherein the second light reflecting portion is smaller than the first light shielding portion so that the second light reflecting portion is not observed from a front surface of the translucent substrate.

6. A display device comprising:

a display panel having a substrate;

a translucent substrate covering the display panel and having a light shielding portion on a periphery of a rear surface of the translucent substrate;

a photo-curable translucent adhesive integrally bonding the translucent substrate and the substrate of the display panel to one another;

a first light reflecting portion formed on the light shielding portion of the translucent substrate; and

a second light reflecting portion formed on the substrate of the display panel so as to oppose the first light reflecting portion through the photo-curable translucent adhesive.

7. A display device according to claim 6 ; further comprising: wherein the substrate of the display panel comprises a first substrate and the display panel has a second substrate; and further comprising a liquid crystal layer sandwiched between the first substrate and the second substrate and a polarizing plate attached to the first substrate.

8. A display device according to claim 6 ; wherein the display panel substrate comprises a color filter substrate; and further comprising a black matrix formed on the color filter substrate, the second light reflecting portion being formed between the black matrix and the color filter substrate.

9. A display device according to claim 6 ; wherein the display panel substrate has color filters;

and further comprising a black matrix formed on a surface of the display panel substrate, a second light shielding portion being formed between the black matrix and the display panel substrate.

10. A display device according to claim 6 ; wherein the second light reflecting portion is smaller than the light shielding portion so that the second light reflecting portion is not observed from a front surface of the translucent substrate.
