1. A liquid crystal display, comprising:

  • a backlight unit comprising a light source comprising a blue light source;

    a display panel comprising;

    a first substrate and a second substrate;

    a liquid crystal layer disposed between the first substrate and the second substrate;

    a color filter disposed on the second substrate, the color filter comprising a first color filter comprising a red quantum dot particle, a second color filter comprising a green quantum dot particle, and a third color filter comprising a transparent organic material and scattering particles therein;

    a blue light blocking layer disposed on the second substrate and overlapping the first color filter and the second color filter; and

    a blue light transmitting layer disposed between the color filters and the liquid crystal layer,wherein the blue light blocking layer and the third color filter are disposed on the same surface of the second substrate,wherein the red quantum dot particle is disposed between the blue light transmitting layer and the blue light blocking layer,wherein the green quantum dot particle is disposed between the blue light transmitting layer and the blue light blocking layer, andwherein a light emitted from a region overlapping the first color filter passes through the blue light transmitting layer, the first color filter, the blue light blocking layer and the second substrate in this order.
