Hole is one-to-one face setting, and N is the integer more than or equal to 1 and less than or equal to M.
In the present embodiment, due to the via regions in the liquid crystal display panel, which is also equipped with through-hole, therefore
It will be further increased by the transmissivity of the light of the via regions of the liquid crystal display panel, in other words, light is penetrating the liquid crystal
When the via regions of display panel, transmissivity will be further increased.
Optionally, the aperture of the through-hole of the coloured silk film layer is less than or equal to the aperture of the through-hole of the device array layer.Change one kind
The hole peripheral wall of saying, the through-hole of the coloured silk film layer is located at corresponding via regions in the device array layer along the projection of the first direction
It is interior.
Optionally, the inner wall of the through-hole of the coloured silk film layer is aligned with the inner wall of corresponding through-hole in the device array layer.
The possible embodiment of second with reference to first aspect, under the third possible embodiment, the coloured silk film layer
Including shading black matrix and multiple pixel color stop blocks.The shading black matrix includes multiple light shielding blocks.In other areas of the coloured silk film layer
Domain, the light shielding block and the pixel color stop block are arranged alternately.Wherein, other regions of the coloured silk film layer refer in the coloured silk film layer in addition to position
Region except the through-hole of color film layer.
Using this programme, the light transmittance of the transmission region of the liquid crystal display panel can not only be improved, moreover it is possible to ensure the liquid
The display area of LCD panel is normally shown.It is worth noting that, the liquid crystal display panel includes transmission region and viewing area
Domain.In general, other regions other than transmission region are display area in the liquid crystal display panel.
With reference to first aspect or the first aspect the first to the third possible embodiment, it is possible at the 4th kind
Under embodiment, the transmission region of the array substrate is fixed with one or more the first mutually isolated support columns, and this first
Dagger edge extends in the opposite direction with the first party.Wherein, the transmission region of the array substrate is located at the array substrate direction
The side of the color membrane substrates, and the transmission region of the array substrate is located at the region where the through-hole of the device array layer.Simply
For, this first supports the via regions for being rooted in the array substrate, and free end is along the direction contrary with this one
Extend towards the color membrane substrates.Using this programme, it can be ensured that the surface of the liquid crystal display panel is smooth.
Optionally, first support column include along stacked gradually in the opposite direction with the first party grid source electrode layer,
Organic planarization layer and pixel electrode layer.
Further, in first support column, also there is the grid source between the grid source electrode layer and the organic planarization layer
The protective layer of electrode layer.
Still further, should be in the first support column, side of the pixel electrode layer far from the organic planarization layer also has
The protective layer of the pixel electrode layer.
Accordingly it is also possible to say, which includes along the grid stacked gradually in the opposite direction with the first party
