1. A liquid crystal display panel, comprising: a first substrate and a second substrate assembled to form a cell, a plurality of main spacers between the first substrate and the second substrate, and an auxiliary spacer around at least a portion of the plurality of main spacers,
wherein a height of the auxiliary spacer is greater than or equal to a height of each of the plurality of main spacers,
the liquid crystal display panel further comprises: pillows on a side of the first substrate close to the second substrate and each abutting against a corresponding one of the plurality of main spacers, and
an orthographic projection of the main spacer on the first substrate falls within an orthographic projection of a corresponding pillow on the first substrate, and an orthographic projection of the auxiliary spacer on the first substrate does not overlap with the orthographic projection of the pillow on the first substrate,
wherein the first substrate comprises a first base, and the liquid crystal display panel further comprises a light-shielding layer on the first base; and
orthographic projections of both the main spacer and the auxiliary spacer on the first base fall within an orthographic projection of the light-shielding layer on the first base,
wherein the first substrate further comprises a driving circuit layer, a planarization layer and a pixel electrode sequentially disposed on a side of the light-shielding layer away from the first base;
the pixel electrode is electrically coupled to the driving circuit layer through a via hole penetrating through the planarization layer; and
the planarization layer is provided with a recess formed in the via hole, and the pillow is embedded in the recess.
