  • Patent number: 10782470
    Abstract: Disclosed is a display apparatus including a display panel, a light guiding plate disposed behind the display panel, a light source disposed to oppose a side of the light guiding plate, a dichroic filter that selectively transmits blue light disposed to cover a front side of a space between the light source and the side of the light guiding plate, and a black member disposed in front of the dichroic filter. Here, since light emitted forward from the light source toward the dichroic filter is generally absorbed by the black member or incident on the light guiding plate, the occurrence of bright parts caused by light leakage is suppressed.
