Abstract
A reflective liquid crystal display panel including a plurality of pixel units is provided. Each pixel unit includes first and second substrates, one first signal line, four second signal lines, a liquid crystal layer, a first pixel structure, a second pixel structure, a third pixel structure and a fourth pixel structure. The first and second signal lines are disposed on the first substrate. The first, second, third, and fourth pixel structures are electrically connected to one of the four second signal lines respectively and electrically connected to the first signal line, where 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 reflection area ratio of the first, second, third, and fourth pixel structures is one of 1:2:4:8 and 2:1:4:8. The second substrate is located opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The display panel displays 16 gray scales to achieve good visual effect.
