DISPLAY DEVICE WITH ONE BACKLIGHT UNIT

Abstract

A display device with a backlight unit is provided. The backlight unit can provide light for a liquid crystal panel. For example, the backlight unit can include blue light sources (212) arranged side by side on the optical substrate. A color conversion film (240) can be stacked sequentially on the blue light sources (212). The color conversion film (240) can emit light of a color other than blue in all directions by utilizing the blue light emitted by the blue light sources (212). The blue light can be scattered in all directions by the color conversion film (240). Thus, the appearance of spots in the display device due to the difference in the direction of propagation of blue light and light of a color other than blue can be prevented.
