A display device, comprising a liquid crystal display panel (3) and a backlight source (2), and further comprising multiple band-pass filters (1) that are disposed in the display device and correspond to pixel units of the liquid crystal display panel (3). The band-pass filters (1) are configured to perform narrow-band filtering on an emergent light of the backlight source (2). By means of the band-pass filters (1), narrow-band filtering is implemented on tricolor lights of red, green, and blue by using a narrow-band interference filtering method, thereby improving the color gamut of the device, and achieving high-color-gamut displaying. |
