Abstract: A display device (liquid crystal display device 100) includes a display panel (10) (liquid crystal panel 10), light receiving sensors (first light receiving sensors 122), and an image changing section (250). A display region (10a) of the liquid crystal panel (10) has a plurality of pixels (30) located therein. The first light receiving sensors (122) receive external light directed to the liquid crystal panel (10), at a plurality of positions in the display region (10a). In the image changing section (250), a reference value is predefined for light receiving information (a1 through d1) obtained by the first light receiving sensors (122). When light receiving information (a1 through d1) exceeding the reference value is obtained by the first light receiving sensors (122), the image changing section (250) changes an image to be displayed on the display region (10a), based on the light receiving information (a1 through d1).

Abstract: A light guide element (7) including a light-emitting section (7b) having a light-emitting surface (7a) which allows light emitted from a dot-like light source (6) to produce a surface emission; an light guide section (7c) for guiding the light emitted from the light source (6) to the light-emitting section (7b); and diffusing means (9) for diffusing incident light, wherein the diffusing means (9) is provided in at least part of a region extending from (i) a boundary surface (8) between the light-emitting section (7b) and the light guide section (7c) to (ii) a halfway point between the boundary surface (8) and that end of the light guide section (7c) which is closer to the light source (6). Thus, it is possible to realize: a light guide element which can suppress a decrease in luminance of surface emission and further improve uniformity in luminance of a light-emitting surface as seen from any angle; an illumination device including such an light guide element; and a liquid crystal display device including such an illumination device and thereby having improved display quality.
