Embodiment 1
[0042] Such as Figure 4 As shown, the display device includes a direct-type backlight module and a display module, and the LED light source is a blue light source. The specific structure of the direct-type backlight module and the display module is shown in the figure, and the light conversion film is a quantum dot film , in the direct-type backlight module, the light-absorbing film is arranged on the surfaces of the four side reflective films, and the light-absorbing film arranged on each side reflective film only covers part of the surface of the side reflective film, wherein the wavelength of light absorbed by the light-absorbing film is 590-610nm, the light-absorbing material of the light-absorbing film is a dye.
Embodiment 2
[0044] The difference from Embodiment 1 is that the light-absorbing film of each side reflective film covers the entire surface of the side reflective film.
