FIELD OF INVENTION

The present invention relates to a field of display technologies, specifically relates to a display substrate and a display panel.

BACKGROUND OF INVENTION

In industries of display panels, usually sub-display panels of various sizes are manufactured in a large panel. difference between areas of pixels of sub-display panels of different sizes is excessively large.

SUMMARY OF INVENTION

Technical Issue

However, a display layer of each display panel is manufactured by the same process. Because a display layer with a greater pixel area requires more material of the display layer and a display layer with a smaller pixel area requires less material of the display layer, the display layer of the display panel with the smaller pixel area has a greater thickness such that difference between heights of display substrates for sub-display panels of different sizes is excessively large to lower flatness of the display substrate.

Technical Solution

The embodiment of the present invention provides a display substrate and a display panel reducing a difference between heights of display layers of sub-display panels of different sizes to improve flatness of the display substrate.

The embodiment of the present invention provides a display substrate, comprising:

an underlay substrate;

a limiting layer disposed on the underlay substrate, wherein the limiting layer comprises a plurality of first limiting portions disposed at intervals and a plurality of second limiting portions disposed at intervals;

a plurality of first display portions, wherein each of the first display portions is disposed in a gap between adjacent two of the first limiting portions and on the adjacent two first limiting portions; and

a plurality of second display portions, wherein each of the second display portions is disposed in a gap between adjacent two of the second limiting portions and on the adjacent two second limiting portions, wherein the gap of the adjacent two first limiting portions is greater than the gap of the adjacent two second limiting portions;

wherein a difference between a height of a top of the second display portions and a height of a top of the first display portions is less than a predetermined difference.

The embodiment of the present invention also provides a display panel, comprising a first sub-display panel and a second sub-display panel, wherein an area of each of sub-pixels in the first sub-display panel is greater than an area of each of sub-pixels in the second sub-display panel, the sub-pixels of the first sub-display panel correspond to the first display portions in position, the sub-pixels in the second sub-display panel correspond to the second display portions in position, each of the first sub-display panel and the second sub-display panel comprises the above display substrate.

Advantages

The display substrate and the display panel of the embodiment of the present invention, comprises an underlay substrate; a limiting layer disposed on the underlay substrate, wherein the limiting layer comprises a plurality of first limiting portions disposed at intervals and a plurality of second limiting portions disposed at intervals; a plurality of first display portions, wherein each of the first display portions is disposed in a gap between adjacent two of the first limiting portions and on the adjacent two first limiting portions; and a plurality of second display portions, wherein each of the second display portions is disposed in a gap between adjacent two of the second limiting portions and on the adjacent two second limiting portions, wherein the gap of the adjacent two first limiting portions is greater than the gap of the adjacent two second limiting portions; wherein a difference between a height of a top of the second display portions and a height of a top of the first display portions is less than a predetermined difference. Because the difference between the height of the top of each of the second display portions and the height of the top of each of the first display portions is less than the predetermined difference, flatness of the display substrate and display effect are improved.
