Display device and illumination device

A display device provided with a display panel and an illumination section that illuminates the display panel, the illumination section comprising:

• a light guide plate having a first surface and a second surface facing each other, the light guide plate having a light entry section and a light guide section in which the light entry section has a tapered shaped portion that extends from the light guide section and terminates in an end surface;
• a light source facing and adjacent the end surface of the light entry section of the light guide plate so as to emit light into the tapered shaped portion of the light entry section;
• an adhesive layer formed adjacent to the first surface of the light guide plate and having substantially the same refractive index as a refractive index of the light guide plate;
• a light reflection layer bonded to the first surface of the light guide plate with at least the adhesive layer in between;
• a low refractive index layer between, and provided adjacent to, the adhesive layer and the light reflection layer, such that the low refractive index layer and the adhesive layer are in an integrated stack configuration with the light guide plate and the light reflection layer, and in which the low refractive index layer extends from a surface of the adhesive layer facing the light reflection layer, to form an interface co-extensive with the surface of the adhesive layer;
• and
• an optical sheet disposed on the second surface of the light guide plate and including a curved section arranged to abut a corner section of the second surface of the light guide plate.
