Light and green glow.Optionally, the light source 20 in the present embodiment is the light emitting diode of transmitting blue light.
Based on this, under the irradiation of the blue light in light source 20 outgoing for the part quantum dot in quantum dot film layer 21, produce green glow,
HONGGUANG, these HONGGUANG, green glow and quantum dot film layer 21 transmission is produced under the irradiation of the blue light in light source 20 outgoing for other quantum dots
Blue light formed white light.These white lights, after array base palte 3, liquid crystal layer 4 and corresponding color blocking, form red respectively
Light, green glow and blue light, these HONGGUANG, green glow and blue light constitute display device image to display.
Display device provided in an embodiment of the present invention, color membrane substrates include color blocking layer and are located at the flat of the surface of color blocking layer
Change layer, wherein, planarization layer includes the first planarization area and the second planarization area around the first planarization area.First planarization
Area is transparent region, and the second planarization area is the region with the first color, so that the first planarization area and the second planarization area
The light of transmission is all white light.Based on this, when the light that the marginal area of quantum dot film layer in backlight module passes through is partially blue, tool
Have the first color second planarizes the color that area can adjust inclined blue light line, and for example, when the first color is yellow, blue light is saturating
White light can be become after crossing the planarization layer of yellow, partially blue such that it is able to solve the display image of liquid crystal indicator marginal area
