1. A grating, comprising:
a first substrate and a second substrate disposed opposite to the first substrate;
a grating electrode layer disposed on the first substrate, wherein the grating electrode layer includes a plurality of grating electrodes and an extension direction of the plurality of grating electrodes is a first direction; and
a supporting structure including a plurality of first supporting pillars,
wherein:
a length of a first supporting pillar along a third direction is a maximum length L12 of the first supporting pillar;
a length of the first supporting pillar along a fourth direction is a maximum width W12 of the first supporting pillar;
the third direction and the fourth direction are both parallel to a plane where the first substrate is located;
an angle between the first direction and the third direction is α;
L12>W12; and
0≤α<45°.
