Step S2, the first heat cure flatness layer 122 is made on color film substrate 121.
Specifically, the first heat cure flatness layer 122 is to use heat cure, blueness resistance material will not be damaged, can had
Effect reduces liquid crystal display panel 10a, 10b and shows blue picture mura risks.
Step S3, the support block 123 on the first heat cure flatness layer 122.
Specifically, support block 123 includes top surface 101 and the side 102 being connected with top surface 101, the thermosetting of side 102 and first
The within angle changed between flatness layer 122 is less than 80 °.Support block 123 and black matrix 121b is overlapped up and down, it is preferable that support
Block 123 is correspondingly arranged in black matrix 121b corner or neighboring area.
Step S4, electrode layer 124 is made on the first heat cure flatness layer 122, and electrode layer 124 is covered in the first heat
Solidify in flatness layer 122 and support block 123.
Specifically, electrode layer 124 includes the area of coverage 103 and non-coverage area 104, and the area of coverage 103 is arranged at the first heat cure
Between the heat cure flatness layer 128 of flatness layer 122 and second, non-coverage area 104 is arranged in support block 123.Electrode layer 124 it is non-
The area of coverage 104 extends to array base palte 14 by support block 123, and is electrically connected with array base palte 14.Electrode layer 124 is used to control
Liquid crystal display panel 10a, 10b enter row wide-narrow view angle switch, by applying different control voltages, liquid crystal on electrode layer 124
Display panel 10a, 10b can be switched between wide viewing angle pattern and narrow viewing angle pattern.
Step S5, makes the second heat cure flatness layer 128 on electrode layer 124, and one end of wherein support block 123 protrudes from
Second heat cure flatness layer 128.
Specifically, the second heat cure flatness layer 128 does not cover spacer block (Spacer), and wherein spacer block is used to support array
Substrate 14.Because the second heat cure flatness layer 128 uses heat cure, the 3rd color blocking layer (blueness resistance material) will not be caused brokenly
It is bad, it can effectively reduce liquid crystal display panel 10a and show blue picture mura risks.The second heat cure is made on electrode layer 124 to put down
During smooth layer 128, because the height of support block 123 is higher, the second heat cure flatness layer 128 of liquid has mobility, therefore
Second heat cure flatness layer 128 without being adhered in the non-coverage area 104 of electrode layer 124.Due to the side 102 of support block 123
Angle between the first heat cure flatness layer 122 is less than 80 °, can guarantee that the area of coverage 103 and non-coverage area of electrode layer 124
104 do not break.
In the present embodiment, the step of making electrode layer 124 also includes：
Step S41, first electrode 125 is made on the first heat cure flatness layer 122.
Step S42, metal conductive strips 127 are made in first electrode 125.
Step S43, second electrode 126 is made in first electrode 125, and metal conductive strips 127 is electrically connected to first
Between electrode 125 and second electrode 126.
Specifically, metal conductive strips 127 are used for the conductance for improving electrode layer 124, avoid the resistance because of electrode layer 124 from bearing
Carry larger, larger in signal course of conveying signal delay, voltage waveform may distortion in course of conveying so that wave distortion or
Signal attenuation causes the problems such as display image quality exception.
Color membrane substrates 12a, 12b of the present invention the first heat cure flatness layer 122 are arranged on color film substrate 121, are supported
Block 123 is arranged on the first heat cure flatness layer 122, and electrode layer 124 is covered in the first heat cure flatness layer 122 and support block
On 123, the second heat cure flatness layer 128 is arranged on electrode layer 124, and one end of support block 123 protrudes from the second heat cure and put down
Smooth layer 128.Because the first heat cure flatness layer 122 and the second heat cure flatness layer 128 are to use heat cure, blueness will not be hindered
Material damages, and can effectively reduce liquid crystal display panel 10a, 10b and show blue picture mura risks.Moreover, the coloured silk of the present invention
Ilm substrate 12a, 12b need not make the conducting resinl electrically connected for array base palte 14, reduce cost of manufacture.
