Ilm substrate has viewing area and non-display area.When the viewing area of light directive color membrane substrates, color membrane substrates realize that illuminated state is shown, when
The non-display area of light directive color membrane substrates, color membrane substrates realize that dark-state is shown.
In above-mentioned liquid crystal display device, the light shafts that backlight assembly issues are converted to polarised light after polarization components 2, then
Change the direction of propagation of light through liquid crystal structure, last light interferes through polarizing coating and realizes angle deviation, so that light shines
It is mapped to viewing area or the non-display area of color membrane substrates, when the viewing area of light directive color membrane substrates, realizes that illuminated state is shown, works as light
The non-display area of directive color membrane substrates realizes that dark-state is shown.As can be seen that in the liquid crystal display device, by changing incidence certainly
The polarization state of right light realizes that the grayscale of color membrane substrates is shown, more accurately liquid crystal control is realized in a manner of simpler liquid crystal drive
System, is advantageously implemented more accurately grayscale and shows.
Further, as shown in Figure 1, the backlight assembly in the present embodiment includes glass substrate 11, light source 12 and takes light
Grating；There are two opposite total reflection surfaces for the tool of glass substrate 11；Light source 12 is set to the side of glass substrate 11；Take light grating
13 are set to total reflection surface of the glass substrate 11 towards 2 side of polarization components.
Glass substrate 11 is plate planar structure, two opposite surface is respectively total reflection surface, so that light is in glass
Total reflection is realized in glass substrate 11.Therefore, the original light for being set to the sending of light source 12 of 11 side of glass substrate enters glass
It is constantly reflected between two opposite total reflection surfaces of glass substrate 11 after substrate 11.
The total reflection surface for being set to glass substrate 11 towards polarization components 2 sides takes light grating 13 to destroy initial light
The total reflection of line is propagated, and changes the light direction of propagation, so that light asks for the position of light grating 13 perpendicular to glass
Light shafts are projected to color membrane substrates in the direction of substrate 11.
The light that light source 12 issues injects glass substrate 11 from the side of glass substrate 11, due to two of glass substrate 11
Surface is total reflection surface, and light is propagated in 11 inner total reflection of glass substrate, is set to the one of total reflection of glass substrate 11
Surface takes light grating 13 that the total reflection of light can be propagated to destruction so that light asks for light grating 13 perpendicular to glass lined
Light is converted and is obtained the light of angle offset, works as light by bottom 11 and the direction injection for deviating from glass substrate 11, polarization components 2
The viewing area of directive color membrane substrates realizes that illuminated state is shown, when the non-display area of light directive color membrane substrates, realizes that dark-state is shown.
Height change brought by light grating 13 is taken in order to flat, glass substrate 11 is arranged towards the side of polarization components 2
There is and take the flatness layer 14 of light grating same layer, facilitates the setting of polarization components 2.
Specifically, as shown in Figure 1, color membrane substrates include the coloured silk for being set in turn in polarization components 2 and deviating from backlight assembly side
