1. A display apparatus comprising:
- a display panel including a plurality of pixels laid out on the surface of a pixel area of said display panel; and
an illumination section configured to generate illumination light in a normal direction perpendicular to said display panel, whereinsaid illumination section hasa light source for radiating original light anda light guiding board which is exposed to a surface of said display panel,said original light generated by said light source hits an incidence surface of said light guiding board and said original light hitting said incidence surface is guided to a radiation surface of said light guiding board to be radiated from said radiation surface as said illumination light,said display panel also includesa plurality of photo sensor devices also arranged in said pixel area to serve as devices each used for receiving incoming light propagating in a direction parallel to the direction from a front-surface side of said display panel to a rear-surface side of said display panel and functions as a panel configured to display an image in said pixel area on said front-surface side,said light source includesan invisible light source for generating an invisible light beam as said original light,said light guiding board includesan invisible light beam reflection section configured to reflect said invisible light beam generated by said invisible light source in a direction parallel to said direction from said rear-surface side of said display panel to said front-surface side of said display panel,said invisible light beam reflection section is provided at a location corresponding to an area included in said pixel area in which said photo sensor devices are created, andsaid invisible light beam reflected by said invisible-light beam reflection section is radiated from said radiation surface of said light guiding board as said illumination light.

18. An illumination apparatus employing:
-
an illumination section configured to generate illumination light in a normal direction perpendicular to a display panel provided with a plurality of pixels, which are laid out on the surface of a pixel area, and provided with a plurality of photo sensor devices, which are also arranged in said pixel area to serve as devices each used for generating received-light data by receiving incoming light propagating in a direction parallel to a direction from a front-surface side of said display panel to a rear-surface side of said display panel, to serve as a panel configured to display an image on said front-surface side, wherein said illumination section has a light source for radiating original light and a light guiding board which is exposed to a surface of said display panel so as to direct said original light generated by said light source to hit an incidence surface and guide said original light hitting said incidence surface to a radiation surface to be radiated from said radiation surface as said illumination light, said light source includes an invisible light source for generating an invisible light beam as said original light, said light guiding board includes an invisible light beam reflection section configured to reflect said invisible light beam generated by said invisible light source in a direction parallel to a direction from said rear-surface side of said display panel to said front-surface side of said display panel, said invisible light beam reflection section is provided at a location corresponding to an area included in said pixel area in which said photo sensor devices are created, and said invisible light beam reflected by said invisible-light beam reflection section is radiated from said radiation surface as said illumination light.
