1. A display panel, comprising:
an array substrate;
a color film substrate disposed opposite to the array substrate;
support pillars disposed between the array substrate and the color film substrate, wherein the support pillars comprise a primary support pillar disposed at a side of one of the array substrate or the color film substrate and abutting against a surface of the other of the array substrate or the color film substrate, wherein the primary support pillar comprises a first support pillar;
pixel sub-units arranged in an array;
scan lines extending in a first direction; and
data lines extending in a second direction,
wherein the first direction and the second direction intersect each other, the pixel sub-units are formed by crossing the scan lines and the data lines, the pixel sub-units each comprise a thin film transistor and a pixel electrode, the thin film transistor comprises a gate, a source and a drain, the scan line is electrically connected to the gate, the data line is electrically connected to the source, and the pixel electrode is electrically connected to the drain;
wherein in the first direction, a projection of the first support pillar in a direction perpendicular to a plane of the display panel is located between projections of two adjacent data lines in the direction perpendicular to the plane of the display panel, and in the second direction, the projection of the first support pillar in the direction perpendicular to the plane of the display panel is located at a side of a projection of the scan line in the direction perpendicular to the plane of the display panel;
wherein the support pillars further comprise auxiliary support pillars, the primary support pillar has a height greater than the auxiliary support pillars in the direction perpendicular to the plane of the display panel, and the auxiliary support pillars comprise the first support pillar; and
wherein in the direction perpendicular to the plane of the display panel, among the first support pillars disposed, a projection of the primary support pillar does not overlap with a projection of the pixel electrode, and a projection of the auxiliary support pillar overlaps with the projection of the pixel electrode.
