Liquid crystal display

A liquid crystal display, comprising:

• a backlight module including a plurality of light emitting diodes arranged at intervals from each other, each of the light emitting diodes being configured to emit a first light, wherein the first light is a violet or near-ultraviolet light having a wavelength greater than 370 nanometers and less than 440 nanometers;
• a reflective filter film disposed on a side of the backlight module to receive the first light, wherein the reflective filter film has following spectral characteristics:
• the reflective filter film allows light beams within a first wavelength range to at least partially pass therethrough, wherein the first wavelength range is between 370 nanometers and 450 nanometers;
• the reflective filter film is configured to at least partially block light beams within a second wavelength range from passing therethrough and reflecting the light beams within the second wavelength range, wherein the second wavelength range is between 450 nanometers and 900 nanometers;
• wherein a light reflectance of the reflective filter film for the light beams within the second wavelength range is greater than or equal to 75%;
• and
• a wavelength conversion film disposed on a side of the reflective filter film away from the backlight module, wherein the wavelength conversion film is configured to convert a wavelength of the first light to form a second light;
• wherein the second light includes at least one of red light, green light and blue light,
• wherein the second light has a wavelength of between 450 nanometers and 900 nanometers and does not overlap with the wavelength of the first light;
• wherein, when the second light encounters the reflective filter film after being reflected, at least 75% of the blue light of the second light is reflected by the reflective filter film and does not return to the backlight module.
