摘要： A method of making a micro corner cube array includes the steps of: preparing a substrate, at least a surface portion of which consists of cubic single crystals and which has a surface that is substantially parallel to {111} planes of the crystals; and etching the surface of the substrate anisotropically, thereby forming a plurality of unit elements for the micro corner cube array on the surface of the substrate. Each of these unit elements is made up of a number of crystal planes that have been formed at a lower etch rate than the {111} planes of the crystals.

摘要： A display device includes a reflector in which a plurality of elements, each including a number of reflective regions, is arranged. In the reflector, the reflective regions of each said element are disposed so that at least part of incoming light, which has been incident on the element, is reflected by each one of the reflective regions after another and then allowed to go out of the element. At least one of the reflective regions of each said element includes: a light reflective plane; and a light modulating layer that is formed on one side of the light reflective plane so as to face the incoming light.

摘要： A reflective display device includes a switching layer, placed between substrates, for switching between a transmissive state for allowing transmission of incident light and a scattering state for scattering the incident light, and a retro-reflector for reflecting an incident ray from the liquid crystal layer so that an outgoing ray of the reflected light is parallel to the incident ray. A pitch of smallest unit structures of the retro-reflector is set to be larger than 0 mm and not more than 5 mm. The retro-reflector is preferably in a form of a corner cube array and has light absorbing surface portions at borders of the smallest unit structures. With this reflective display device, brightness of white state and contrast ratio can be improved.

摘要： In a luminous display element, a retro-reflector is provided on the back side of an organic EL layer which includes an emission layer whose state changes between an emission state and a non-emission state. The retro-reflector includes a corner cube array, and reflects incident light in the same direction as an incident direction. A unit structure of the corner cube array is a form of a triangular pyramid which is made up of rectangular equilateral triangles having three faces, and a light shielding process is performed on the periphery of a base angle of the rectangular equilateral triangle. Thus, it is possible to prevent an image from being reflected, so that it is possible to provide the luminous display element whose contrast ratio and the utilization efficiency of emission are high.

摘要： A laminated phase plate is formed by laminating a first optical phase difference compensation plate, having a retardation between 100 and 180 nm for transmitted light, with a wavelength of 550 nm and a second optical phase difference compensation plate having a retardation between 200 and 360 nm for transmitted light with a wavelength of 550 nm. The optical phase difference compensation plates are arranged so that |&thgr;1−(2×&thgr;2)| is between 80 and 100 degrees. The term &thgr;1 is an angle between a vibration direction of linearly polarized light and a slow axis direction of the first optical phase difference compensation plate when the linearly polarized light, which is visible light and has a fixed plane of vibration, is incident on the second optical phase difference compensation plate. The term &thgr;2 is an angle between the vibration direction of linearly polarized light incident on the second optical phase difference compensation plate and a slow axis direction of the second optical phase difference compensation plate.
