Antireflective film, method of producing antireflective film, and eyeglass type display

Abstract

The present invention is an antireflective film, including: a support base, and a pattern composed of a photoresist material formed on the support base, the pattern having a larger size at a point closer to the support base. The present invention provides an antireflective film that is able to give antireflection effect to decrease the reflection of light, a method of producing the same, and an eyeglass type display.

Description

TECHNICAL FIELD[0001]The present invention relates to an antireflective film for collecting visible light with a shallow incidence angle without reflecting it and for emitting visible light at a shallow angle without reflecting it, a method of producing the antireflective film, and an eyeglass type display using the antireflective film.BACKGROUND ART[0002]The development of devices for virtual reality (VR) has been advancing. Wearing a goggles type VR, it is possible to watch a movie and to converse with a person remote from each other as if being adjacent to (PATENT LITERATURE 1). It becomes familiar to experience images as if to go beyond space-time, which were shown in SF movies in the past.[0003]In order to obtain real feeling of virtual reality, it has been investigated to reduce the weight and the thickness of the goggles. It is also necessary to replace the pair of goggles itself to an eyeglass type (glasses type), which is lighter in weight, and it will become necessary to c...

Benefits of technology

[0055]As described above, in the antireflective film of the present invention, a moth eye-type antireflective film is successfully formed with a pattern in a tapered profile formed by exposure and development using a photoresist based on a highly refractive polymer. This makes it possible to obtain antireflective effect, which exhibits lower reflection of visible light even to incident light and emitted light with a shallow angle. Accordingly, when it is combined with a lens(es) with a high refractive index, light emitted from liquid crystal, organic EL, and micro LED that are installed near eyes can be seen in the state of higher contrast and higher brightness. The inventive method of producing an antireflective film makes it possible to form the inventive antireflective film easily. Moreover, using the inventive antireflective film, it is possible to realize an eyeglass type display which is substantially light in weight and thin compared to previous head mount displays.

Problems solved by technology

The imprint method involves a drawback of wearing of the printing block, which makes it impossible to form a pattern.

The moth eye structure itself involves a problem that the antireflective function lowers when a foreign matter sticks to the pillars or the pillar breaks.
