As shown in fig. 2a, fig. 2b, fig. 3, fig. 4, fig. 5a, fig. 5b, fig. 6a and fig. 6b, a passive vertical alignment full-view liquid crystal display includes a first glass substrate 1 and a second glass substrate 2 disposed in parallel and opposite to each other at an interval, a first ITO layer 4 having a plurality of circular holes 3 is disposed on a surface of the first glass substrate 1 opposite to the second glass substrate 2, and the plurality of circular holes 3 are distributed in the first ITO layer 4 in an array form; a second ITO layer 6 with a plurality of strip-shaped holes 5 is arranged on one surface, opposite to the first glass substrate 1, of the second glass substrate 2, and the strip-shaped holes 5 are distributed in the second ITO layer 6 in an array form; the round holes 3 and the strip-shaped holes 5 are arranged in a staggered manner; a first orientation layer 7 is coated on the first ITO layer 4, and the first ITO layer 4 is wrapped between the first glass substrate 1 and the first orientation layer 7; a second orientation layer 8 is coated on the second ITO layer 2, and the second ITO layer 6 is wrapped between the second glass substrate 2 and the second orientation layer 8; the first alignment layer 7 and the second alignment layer 8 are both non-rubbed alignment layers; liquid crystal molecules 9 are filled between the first alignment layer 7 and the second alignment layer 8.
In this particular embodiment:
specifically, the circle center of the circular hole is opposite to the center between two corresponding adjacent strip-shaped holes in the width direction of the strip-shaped hole. Specifically, as shown in FIG. 4, the diameter of the circular holes is 10 μm, and the size of the strip-shaped holes is 50X 10 μm. In the length direction of the strip-shaped holes, the distance between any two adjacent strip-shaped holes is 30 micrometers; in the width direction of the strip-shaped holes, the distance between any two adjacent strip-shaped holes is 70 μm.
In a passive vertical alignment full-viewing-angle liquid crystal display according to the present invention, FIG. 2a shows a circular hole 3 formed in a first ITO layer 4, fig. 2b shows the design of a strip-shaped hole 5 in the second ITO layer 6, after the first glass substrate 1 and the second glass substrate 2 are attached, the arrangement and distribution of the round holes 3 in the upper glass substrate 1 and the strip-shaped holes 5 in the second glass substrate 2 are shown in figure 3, after holes are dug on the first ITO layer 4 and the second ITO layer 6, after the power is switched on, because the first glass substrate 1 and the second glass substrate 2 are not a whole electrode any more, the direction of the electric field can deflect to the position with ITO, a certain angle of deflection can be formed, the deflection direction of the electric field is shown in fig. 5a and 5b (the direction of the divergent arrows around the circular hole 3 in fig. 5a represents the direction of the electric field, and the direction of the arrows in fig. 5b represents the direction of the electric field); specifically, the electric field is diverged to the periphery by taking the circular hole 3 as a center to form a divergent electric field with a certain angle; after the passive vertical alignment full-viewing-angle liquid crystal display is electrified, the distribution of liquid crystal molecules 9 and the distribution of an electric field are as shown in fig. 7 (the direction indicated by an arrow between the liquid crystal molecules 9 in fig. 7 is the direction of the electric field), and holes with different shapes are designed on the routing lines of the display ITO, so that the passive vertical alignment full-viewing-angle liquid crystal display has the advantages that the direction of the electric field after the electrification is not the vertical electric field from top to bottom, but the distribution of the liquid crystal molecules and the distribution of the electric field are as shown in fig. 6b and fig. 7 (when the passive vertical alignment full-viewing-angle liquid crystal display is not electrified, the distribution of the electric field is as shown. The first alignment layer 7 and the second alignment layer are alignment layers that are not rubbed, so that the pretilt angles of the alignment layers are the same in each direction and are not biased in one direction. Under the two conditions that the holes influence the electric field distribution and the frictionless orientation layer, the electrified liquid crystal molecules 9 incline towards the periphery to form multi-domain liquid crystal display, namely full-view display.

In this particular embodiment:
specifically, the step S1 is,
