ABSTRACT:
An LCD panel includes a first substrate, a second substrate, alignment protrusions and a liquid crystal layer between the first substrate and the second substrate. The first substrate includes pixel units arranged in an array. Each of the pixel units has at least one reflection area and one transmittance area. The first substrate has concaves in the reflection areas. The second substrate is above the first substrate. The first substrate or the second substrate has at least one padding layer in the reflection area. The alignment protrusions having approximately the same height are disposed on the second substrate and located in centers of each of the reflections and the transmittance areas. In the reflection area, a group of the alignment protrusions are in the concaves to keep a gap from the first substrate. The other group of the alignment protrusions outside of the concaves contact with the first substrate directly.
