In the case where the embodiment of the present application range, the first viewing area can also be referred to as the second viewing area, similarly, the second viewing area
The first viewing area can also be referred to as.
It is former to the display of display panel below in order to clearly illustrate color membrane substrates provided by the embodiment of the present application
Reason is illustrated.
Display panel includes the color membrane substrates being oppositely arranged and array substrate, is aobvious between color membrane substrates and array substrate
Show the liquid crystal layer of panel, is provided with liquid crystal molecule in liquid crystal layer.It is additionally provided with support column between color membrane substrates and array substrate, uses
The thickness of liquid crystal cell between control color membrane substrates and array substrate.
The viewing area array arrangement of display panel has sub-pixel SP, multiple sub-pixel SP to form a pixel PX, a picture
Multiple sub-pixel SP included by plain PX issue the light of varying strength, different colours, after light mixing, so that entire pixel PX is corresponding
In showing the pixel in image, the light that multiple pixel PX on display surface are issued forms image.
Array substrate is provided with array arrangement corresponding to the sub-pixel PX of array arrangement in the side close to color membrane substrates
Thin film transistor (TFT).Electric field is formed between pixel electrode and public electrode in thin film transistor (TFT), drives the liquid crystal in liquid crystal layer
Molecule turns to, so that the steering of the liquid crystal molecule of the corresponding region different subpixel PX is different, and the different liquid crystal molecules pair turned to
It is different in the transmitance of light.That is, the electric field that thin film transistor (TFT) generates can be controlled by controlling the steering of liquid crystal molecule
Make the intensity of the light across liquid crystal molecule.
Color membrane substrates are provided with array arrangement corresponding to the sub-pixel PX of array arrangement in the side close to array substrate
Color blocking unit.
Display panel shines for passive type, i.e. side of the array substrate far from color membrane substrates, is provided with backlight module, backlight
Mould group issues equal white light, after the liquid crystal molecule different across the steering of the corresponding region different subpixel SP, different subpixel SP
The light intensity of corresponding region generates difference.
And after the different white light of intensity is each passed through different subpixel SP and corresponds to color blocking unit, that is, become intensity it is different,
The different light of color, so that different subpixel SP issues the light that intensity is different, color is different.
Based on the explanation of the displaying principle to display panel, it is recognised that the display effect of the display surface of display panel takes
Certainly in the illumination effect of the sub-pixel SP of array arrangement, and the illumination effect of each sub-pixel SP, it is corresponding to depend on sub-pixel SP
The steering of the liquid crystal molecule in region.
Liquid crystal is a kind of soft substance between liquid and solid-state, is injected in liquid crystal cell by way of perfusion, once
The shape of liquid crystal cell changes, then liquid crystal is distributed corresponding change also in display panel.It is color when display panel is normally shown
The thickness of liquid crystal cell between ilm substrate and array substrate is uniform, correspondingly, the liquid crystal molecule of the corresponding region different subpixel SP
Thickness it is also identical so that the display surface of entire display panel is shown uniformly.When display panel is squeezed by the external world, coloured silk is needed
The support column being arranged between ilm substrate and array substrate is supported, and keeps the uniform of the thickness of liquid crystal cell, so that different sub- pictures
The thickness of the liquid crystal molecule of the plain corresponding region SP keeps uniform.
Since support column needs black matrix" to be blocked, and black matrix" is used to be spaced different color blocking units, therefore,
Orthographic projection of the support column on underlay substrate exists from orthographic projection of the contact portion of different color blocking units on underlay substrate and hands over
It is folded.And in the manufacturing process of display panel, different color blocking units different perpendicular to the thickness on underlay substrate direction so that
Support column and the first planarization layer contact area out-of-flatness, support column cannot be arranged along the direction perpendicular to display panel, exist
Inclination, the height of support column and the thickness of liquid crystal cell are unequal, cannot highly accurately control liquid crystal cell by support column
Thickness influences display effect so that liquid crystal cell is in uneven thickness.

With expansion section BM2, it need to only increase in the corresponding position of mask plate MASK and be open, it is therefore, entire black without increasing additional step
Colour moment battle array BM (including main part BM1 and expansion section BM2) is equal perpendicular to the thickness in the first plane.
Specifically, in the another kind color membrane substrates provided by the embodiment of the present application, along perpendicular to the first plane direction,
Color blocking layer with a thickness of D1, black matrix" BM with a thickness of D2, D1 > D2.
It is appreciated that the thickness of each color blocking unit 112 is both greater than the thickness of black matrix" BM in color blocking layer.Although support
The region that column 114 is arranged cannot have color blocking unit 112, i.e. color blocking unit cannot cover the main part BM1 of black matrix" BM, but color
Resistance unit 112 can but cover the expansion section BM2 of black matrix" BM.
Specifically, color blocking unit 112 includes body part 1121 and edge part 1122, in the direction perpendicular to the first plane
On, body part 1121 is not overlapped with black matrix" BM, after passing through from body part 1121 across the white light of liquid crystal layer, becomes different
The light of color, so that corresponding sub-pixel SP issues the light of different colours.1122 part of edge part covers expansion section BM2, passes through
After the white light of liquid crystal layer is passed through from edge part 1122, the portion BM2 of being extended is blocked.Therefore, it sees on the whole, the covering of color blocking layer part
Black matrix" BM, the first planarization layer 113 cover black matrix" BM and color blocking layer.
It should be noted that 1122 part of edge part is covering expansion section BM2, i.e. edge part 1122 on the first plane just
Projection, close to support column 114 side and far from support column 114 side, the distance between size be X, 0 < X < Y.Wherein,
Y is that the distance between the orthographic projection of orthographic projection and support column 114 on the first plane of body part 1121 on the first plane is big
It is small.
1122 part of edge part covers expansion section BM2, can be avoided when making display panel, due to the error of technique,
So that the orthographic projection of color blocking unit 112 on the first plane, separates with the orthographic projection of expansion section BM2 on the first plane,
Cause light leakage.
