AI Technical Summary

Benefits of technology

The present invention describes an antireflective film that can reduce the reflection of visible light from incident light and emitted light with a shallow angle. This film is particularly useful when combined with a lens with a high refractive index. The invention also provides a simple method for producing the antireflective film, making it easy to create. Additionally, the use of this antireflective film allows for the creation of eyeglass-style displays that are lightweight 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.

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...
