Side, TFT substrate 200 are arranged on colored optical filtering substrates 100 away from backlight side, i.e. the incident light of backlight is to inciding colorized optical filtering
Substrate 100, it is again incident on TFT substrate 200.By taking light A as an example, this is partially due to scan line and data wire electric field disorder nearby are led
Cause emergent light oblique fire caused by liquid crystal disorder, through color blocking layer 130 after be irradiated to reflector layer 150 in the second black matrix 124,
TFT substrate 200 is directly passed after the reflection of reflector layer 150, or finally projects TFT substrate 200 by multiple reflections and is weighed
It is new to utilize, improve the display brightness of liquid crystal panel.Middle backlight illumination is to directly absorbed after black matrix compared with the prior art
For situation, the utilization rate of light is improved.
By taking light B in scheming as an example, wherein the height of black matrix layer 120 is 6 μm, and subpixel size is 21 μm, the first black square
The width of battle array 122 is 5.75 μm, then tan-1(6/21)<θ<tan-1(6/ (21-5.75)), i.e., 15.9 °<θ<21.5 °, θ takes the limit
It is worth for 21.5 °.Imply that and work as θ>At 21.5 °, with the emergent light of left and right color blocking colour mixture will not occur for the emergent light of the limit.In this implementation
In example, θ angles are preferably 20 °~30 °, you can avoid that colour mixture occurs between adjacent color blocking, can also reduce as far as possible because second is black
Matrix 124 influences to caused by Liquid Crystal Molecules Alignment.
It is to be appreciated that black matrix is used to be spaced the color color blocking of red, green, blue three, its main function is those skilled in the art
Prevent bias light from revealing, improve and display contrast, prevent colour mixture and increase the purity of color, the non-pixel areas formed with black matrix
Domain can prevent bias light from revealing, and the pixel region for being formed without black matrix can pass through bias light.In the present embodiment, second
Reflector layer 150 is set in black matrix 124, and it can constantly reflect oblique fire in bias light to the light of the second black matrix 124, make
It improves in the prior art because the light being irradiated in black matrix can not directly be utilized by absorption and cause close to vertical exit
Backlight loss, improve light utilization.
