Display panel

A display panel, comprising:

• a thin film transistor (TFT) layer;
• a pixel definition layer disposed at one side of the TFT layer, the pixel definition layer comprising a plurality of sub-pixel openings, the plurality of sub-pixel openings comprising a plurality of first sub-pixel openings arranged in rows and columns for disposing first-color sub-pixels;
• and
• a spacer layer arranged at one side of the pixel definition layer away from the TFT layer, the spacer layer comprising a plurality of first spacer pillars arranged in rows and columns and distributed according to a first preset rule:
• the plurality of first spacer pillars and the plurality of first sub-pixel openings adjacent to the plurality of first spacer pillars are arranged in one-to-one correspondence, such that the plurality of first sub-pixel openings are arranged in at least two directions around the plurality of first spacer pillars adjacent to the plurality of first sub-pixel openings, wherein for any two adjacent first spacer pillars in a same row, their corresponding first sub-pixel openings are arranged on opposite sides of the row, such that the corresponding first sub-pixel openings are positioned alternately to form a periodic pattern at a first side and a second side of the row of the first spacer pillars;
• wherein the plurality of first spacer pillars comprise a plurality of first sub-spacers and a plurality of second sub-spacers;
• in an adjacent couple of the plurality of first sub-spacers and the plurality of second sub-spacers, the first sub-spacer is arranged at one side of an adjacent one of the plurality of first sub-pixel openings toward a first direction, the second sub-spacer is arranged at one side of an adjacent one of the plurality of first sub-pixel openings toward a second direction, and the second direction forms a first predetermined included angle with the first direction;
• wherein the plurality of sub-pixel openings further comprise a plurality of second sub-pixel openings for disposing second-color sub-pixels, and the first-color sub-pixels and the second-color sub-pixels display different colors;
• the plurality of first spacer pillars and the plurality of second sub-pixel openings adjacent to the plurality of first spacer pillars are arranged in one-to-one correspondence, such that the plurality of second sub-pixel openings are arranged in at least two directions around the plurality of first spacer pillars;
• wherein the spacer layer further comprises a plurality of second spacer pillars distributed according to a second preset rule:
• the plurality of second spacer pillars and the plurality of first sub-pixel openings adjacent to the plurality of second spacer pillars are arranged in one-to-one correspondence, and the plurality of second spacer pillars and the plurality of first spacer pillars adjacent to the plurality of second spacer pillars are arranged in one-to-one correspondence, wherein the plurality of first sub-pixel openings are arranged in at least two directions around the plurality of first spacer pillars adjacent to the plurality of first sub-pixel openings, and the plurality of first sub-pixel openings are arranged in at least two directions around the plurality of second spacer pillars adjacent to the plurality of first sub-pixel openings;
• wherein the plurality of second spacer pillars comprise a plurality of third sub-spacers and a plurality of fourth sub-spacers, wherein in an adjacent couple of the plurality of third sub-spacers and the plurality of fourth sub-spacers, the third sub-spacer is arranged at one side of an adjacent one of the plurality of first sub-pixel openings toward a fifth direction, the fourth sub-spacer is arranged at one side of an adjacent one of the plurality of first sub-pixel openings toward a sixth direction, and the fifth direction forms a third predetermined included angle with the sixth direction;
• wherein in the first sub-spacer and the third sub-spacer adjacent to one of the same plurality of first sub-pixel openings, a fourth predetermined included angle between the first direction and the fifth direction is less than 180 degrees;
• and in the second sub-spacer and the fourth sub-spacer adjacent to one of the same plurality of first sub-pixel openings, a fifth predetermined included angle between the second direction and the sixth direction is less than 180 degrees;
• wherein the fourth predetermined included angle and the fifth predetermined included angle are both 90 degrees.
