Abstract:
Provided are a liquid crystal display device and television receiving apparatus having further improved use efficiency of light emitted from a light source while suppressing increase in costs. A liquid crystal display device 1 of the invention includes a liquid crystal display panel (40), two polarizing layers (first polarizing layer (50), second polarizing layer (52)) disposed so that the two polarizing layers sandwich the liquid crystal display panel, and a backlight device (10) (light source). Between the backlight device (10) and the first polarizing layer (50) (rear polarizing layer) that is one of the two polarizing layers disposed closer to the backlight device (10), an optical sheet assembly (20) is provided, which optical sheet assembly includes a lens sheet (22) for converging light emitted from the backlight. Furthermore, the first polarizing layer (50) and the optical sheet assembly (20) sandwich a λ/2 sheet (30) (λ/2 layer).
