A light beam direction control element includes: a first transparent substrate; a second transparent substrate facing the first transparent substrate; a first conductive film pattern having openings and being formed on a surface of the first transparent substrate opposing the second transparent substrate; a second conductive film pattern having openings and being formed on a surface of the second transparent substrate opposing the first transparent substrate; an electrophoretic element being sandwiched between the first and second conductive film patterns, and including light-shielding electrophoretic particles having a surface charge and a transparent dispersion medium; and light-transmissive regions being disposed between the first and second transparent substrates, being sandwiched between at least a portion of the openings of the first and second conductive film patterns, having a surface parallel to the first and second conductive film patterns, and having side walls surrounded by the electrophoretic element.

Light beam direction control element, display device, and manufacturing method for light beam direction control element

A light beam direction control element includes: a first transparent substrate; a second transparent substrate which is disposed facing the first transparent substrate; light shielding elements which are disposed between the first transparent substrate and the second transparent substrate; light transmission regions which are disposed between the first transparent substrate and the second transparent substrate and whose sidewalls are surrounded by any of the light shielding elements; a resin layer which is disposed between the first transparent substrate and the second transparent substrate, surrounds an outer circumference of a light transmission region pattern formed by the light transmission regions, and includes a sealed first opening unit; and a first buffer region which is sandwiched between a surface including the first opening unit of the resin layer and the light transmission region pattern, and in which the light shielding elements are injected.

Light beam direction control element

Provided is a release film to be in contact with a surface of a base member and a surface of an object between the surface of the base member and the surface of the object. The release film includes a crystalline layer and a debond layer in contact with the crystalline layer. The debond layer has pores and includes an amorphous substance soluble in a solvent.
