Abstract
There are provided optical members having a microlens array structure that can be produced by a more simple process, as well as devices employing them. The optical members have on one main surface a microlens array formed using a replication process that employs a mold comprising a plurality of gas bubbles arranged on a replication surface. There are also provided devices that employ the optical members.
Claims22
An optical member comprising:
- a main surface;
- and
- a microlens array on the main surface, wherein the microlens array is formed using a replication process that employs a mold comprising a plurality of gas bubbles arranged on a transfer surface.
5-6. (canceled)
An optical member comprising:
- a main surface,
- a plurality of convex lenses formed by replication of gas bubble shape, arranged on the main surface, and
- partition walls adjacent to each of the convex lenses and surrounding each of the convex lenses.
An optical member comprising:
- a main surface,
- a plurality of concave lenses formed by replication of gas bubble shape, arranged on the main surface, and
- grooves adjacent to each of the concave lenses and surrounding each of the concave lenses.
11-15. (canceled)
A sheeting comprising:
- a microlens array having a main surface and a plurality of convex lenses formed by replication of gas bubble shape arranged on the main surface, wherein each of the convex lenses is adjacent to and surrounded by partition walls that are higher than the convex lenses;
- a protective material disposed on the microlens array so as to supported by the partition walls;
- and
- a radiation sensitive layer disposed on a surface that is on an opposite side of the main surface of the microlens array.
