Abstract: A liquid crystal display device (100) of the present invention includes an edge light type backlight unit (10) and a liquid crystal panel (20). The backlight unit (10) includes a light guide plate (2) and a light source (1) that emits light to a light entrance end surface (2a) of the light guide plate (2). An opposite end surface (2b), of the light guide plate (2), which is opposite to the light entrance end surface (2a), is shaped to have one or more triangular shape(s) or one or more rounded shape(s) in a cross section both in a thickness direction of the light guide plate (2) and in a peak luminance direction of light from the light source (1). Light parallel to the peak luminance direction, which light is from the light source (1), is suitably reflected without being scattered by an inclined surface of the opposite end surface (2b).

Abstract: A lens cap (3) is arranged to cover a light-emitting surface (23) of a light source (2), the lens thereby guiding light from the light source (2) in oblique directions relative to the light source (2). The lens cap (3) includes, in a planar view, a light transmitting region (33) and a light blocking region (34), the light transmitting region (33) divided into a plurality of light transmitting regions by the light blocking region (34) so that the light from the light source (2) passes through the plurality of light transmitting regions (33) and is separated into beams traveling in different directions.

Abstract: A display device (100) includes a sensor (6A) which measures luminance of light emitted from a display region at an A side of a display section (5), a sensor (6B) which measures luminance of light emitted from a display region at a B side of the display section (5), and an operation section (7) which, in accordance with a result of the measurement by the sensors (6A) and (6B), decreases luminance of an LED (4A) or LED (4B) which illuminates a display region from which light with higher luminance is emitted, and/or increases luminance of an LED (4A) or LED (4B) which illuminates a display region from which light with lower luminance is emitted.

Abstract: A black line inserting section (3) inserts first grayscale inserts first grayscale lines, each of which has a color of certain grayscale and has a width corresponding to a certain number of pixels, into each of first video images such that a certain distance is secured, between the respective first grayscale lines, in a vertical or horizontal direction of each of the first video images. The black line inserting section (3) also inserts second grayscale lines into each of second video images, which corresponds to a certain number of frames and by which a corresponding one of the first video images is followed, such that the second grayscale lines are not inserted into second parts corresponding to first parts where the respective first grayscale lines are inserted.

Abstract: The display device (1) displays, based on at least information indicative of a visual line direction (20) of an observer (2), a three-dimensional video image (18) which (i) varies depending on the visual line direction (20) and (ii) is directing to the observer (2). The observer (2) can view the three-dimensional video image (18) of a three-dimensional object from various angles as if the observer (2) viewed the actual three-dimensional object from various angles.
