ABSTRACT:
A display device of the present invention includes: an illumination device that emits light; first and second substrates provided opposite each other; and the first substrate being disposed closer to the backlight device than the second substrate is; and a plurality of microlenses (2) provided on the surface, opposite the backlight device, of the first substrate, the plurality of microlenses converging light (7) emitted from the illumination device, the first substrate having a plurality of pixels (Px) disposed in a matrix, each of the pixels including: a transparent region (Tr) through which light passes; and a reflective region (Rf) from which light is reflected, wherein the light (7) emitted from the illumination device is converged onto the transparent region (Tr) through the microlens (2), wherein an uneven section (19) with convexities and concavities is provided between the neighboring microlenses (2) on the surface of the first substrate which surface is opposite the illumination device (3). With this arrangement, it is possible to provide a display device which enhances efficiency in utilization of light emitted from the illumination device (backlight) and increases luminance of the display device without such display problems as bright lines and moiré.
