Abstract
A liquid crystal light-control panel includes a first array substrate and a cover plate opposite to each other, and a plurality of support pillars disposed between the first array substrate and the cover plate. The first array substrate includes a first substrate and a plurality of transistors disposed on the first substrate. The cover plate includes a second substrate and a light-shielding layer, including a plurality of first light-shielding blocks in one-to-one correspondence with the plurality of support pillars and a plurality of second light-shielding blocks in one-to-one correspondence with the plurality of transistors, disposed on the second substrate. An orthographic projection of the support pillar onto the first substrate is within an orthographic projection of the corresponding first light-shielding block onto the first substrate. An orthographic projection of the transistor onto the first substrate is within an orthographic projection of the corresponding second light-shielding block onto the first substrate.
