The part risen is arranged in array.
When to orientation is carried out comprising above-mentioned drive circuit layer and the both alignment layers of the display panel of color blocking layer, alignment direction is logical
Often perpendicular to scan line extending direction.
But when carrying out orientation to both alignment layers according to above-mentioned alignment direction using friction cloth, due to same column in color blocking layer
The corresponding friction cloth of protrusion on position it is identical, the hairbrush in friction cloth will receive the raised role of same column and be recessed, because
And will appear friction shadow region, cause the orientation of the corresponding alignment film in same row protrusion two sides weaker, cause pixel edge light leakage,
So as to cause the contrast decline of display picture.
Summary of the invention
In view of drawbacks described above in the prior art or deficiency, it is intended to provide a kind of display panel and the display dress comprising it
It sets, to solve the technical problems existing in the prior art.
In a first aspect, the embodiment of the present application provides a kind of display panel, display panel includes first substrate；First substrate
