Abstract
A reflective LCD panel includes a plurality of pixel units, each of which includes: first and second substrates, first and second scan lines, first and second data lines, a liquid crystal layer, and first, second, third, and fourth pixel structures. The first and second scan lines and the first and second data lines are disposed on the first substrate. Each of the first, second, third, and fourth pixel structures is electrically connected to one of the first and second scan lines and one of the first and second data lines, respectively. The first, second, third, and fourth pixel structures respectively include: an active component and a reflective pixel electrode electrically connected to the active component, and a reflective area ratio of the first, second, third, and fourth pixel structures is 1:2:4:8 or 2:1:4:8. Here, 16 gray scales may be displayed for achieving better visual effects.
