## Abstract

The present invention gives a strong sense of immersion to a user. A head mount display (100) includes: a housing (1); a display section (2) which is provided in the housing and displays an image (I); a lens (3a, 3b) which is provided in the housing and through which the display section (2) is visible to a user; and at least one light emitting section (4) which is provided in the housing (1) and emits light with which to illuminate a circumference of a counter surface (3a-1, 3b-1) of the lens (3a, 3b) which counter surface faces an eye of the user.

## Claims

### Claim 1

A head mount display comprising:
a housing;
a display section which is provided in the housing and displays an image;
a lens which is provided in the housing and through which the display section is visible to a user; and
at least one light emitting section which is provided in the housing and emits light with which to illuminate a circumference of a counter surface of the lens which counter surface faces an eye of the user.

### Claim 2 (depends on 1)

The head mount display as set forth in claim 1, further comprising a light emission color adjusting section configured to analyze a color of the image and adjust, in accordance with an analysis result, a color of the light which is emitted by the at least one light emitting section.

### Claim 3 (depends on 2)

The head mount display as set forth in claim 2, wherein the light emission color adjusting section analyzes a color of an edge region of the image.

### Claim 4 (depends on 1)

The head mount display as set forth in claim 1, wherein the head mount display allows an information processing device including the display section to be provided in the housing.

### Claim 5 (depends on 1)

The head mount display as set forth in claim 1, wherein:
the at least one light emitting section which is provided in the housing comprises a plurality of light emitting sections; and
the circumference of the counter surface is illuminated with the light merely by light emission by a corresponding one of the plurality of light emitting sections.

### Claim 6 (depends on 1)

The head mount display as set forth in claim 1, wherein the at least one light emitting section which is provided in the housing is a light guide plate which guides, to the circumference of the counter surface of the lens, light coming from the display section.
