a display part including a display face and being flexible;
a restriction part comprising a plurality of first convex parts to restrict a bending quantity of the display part; and
an optical control part provided on the display face side of the display part or between the display part and the restriction part to exercise control so as to change light emitted from the display face of the display part according to bending of the display part,
wherein
the optical control part comprises a scattering plate provided on a display face side of the display part, and
the scattering plate is configured so as to make thickness of the scattering plate in a direction perpendicular to the display face small as the display part is bent.
2. The display device according to claim 1 , wherein the optical control part comprises a first organic resin layer having a wave shaped surface, and a second organic resin layer formed so as to cover the surface of the first organic resin layer.
3. A display device comprising:
a display part including a display face and being flexible;
a restriction part comprising a plurality of first convex parts to restrict a bending quantity of the display part; and
an optical control part provided on the display face side of the display part or between the display part and the restriction part to exercise control so as to change light emitted from the display face of the display part according to bending of the display part,
wherein
the optical control part comprises a transparent first support substrate, a plurality of first prisms each having a triangular sectional shape arranged in parallel on the first support substrate, a transparent second support substrate, and a plurality of second prisms each having a triangular sectional shape arranged in parallel on the second support substrate,
the first and second support substrates are arranged so as to cause the first and second prisms to be opposed alternately, and
a distance between the first and second support substrates is decreased as the display part is bent.
4. A display device comprising:
a display part including a display face and being flexible;
a restriction part comprising a plurality of first convex parts to restrict a bending quantity of the display part; and
an optical control part provided on the display face side of the display part or between the display part and the restriction part to exercise control so as to change light emitted from the display face of the display part according to bending of the display part,
wherein
the optical control part comprises a transparent first film substrate, a plurality of first projection parts each having a hemispherical shape arranged on the first film substrate, a transparent second film substrate, and a plurality of second projection parts each having a hemispherical shape arranged on the second film substrate,
the first and second film substrates are arranged so as to cause the first and second projection parts to be opposed alternately, and
a distance between the first and second film substrates is decreased as the display part is bent.
5. A display device comprising:
a display part including a display face and being flexible; and
an optical control part provided on the display face side of the display part or on the opposite side to control so as to change light emitted from the display face of the display part according to the bending quantity of the display part,
wherein
the optical control part comprises a scattering plate provided on a display face side of the display part, and
the scattering plate is configured so as to make thickness of the scattering plate in a direction perpendicular to the display face small as the display part is bent.
6. The display device according to claim 5 , wherein the optical control part comprises a first organic resin layer having a wave shaped surface, and a second organic resin layer formed so as to cover the surface of the first organic resin layer.
7. A display device comprising:
a display part including a display face and being flexible; and
an optical control part provided on the display face side of the display part or on the opposite side to control so as to change light emitted from the display face of the display part according to the bending quantity of the display part,
wherein
the optical control part comprises a transparent first support substrate, a plurality of first prisms each having a triangular sectional shape arranged in parallel on the first support substrate, a transparent second support substrate, and a plurality of second prisms each having a triangular sectional shape arranged in parallel on the second support substrate,
the first and second support substrates are arranged so as to cause the first and second prisms to be opposed alternately, and
a distance between the first and second support substrates is decreased as the display part is bent.
