Abstract
A display panel comprises a first substrate, a second substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a light-shielding layer disposed between the liquid crystal layer and the second substrate, plural spacers, and an alignment film disposed between the first substrate and the second substrate. The alignment film comprises a first region near the spacer and a second region adjacent to the first region. The second region is positioned outside the first region and corresponds to the light-shielding layer. The first region has a first phase value (S1) and a first roughness value (R1). The second region has a second phase value (S2) and a second roughness value (R2). The ratio (S1/R1) of the first phase value to the first roughness value is larger than the ratio (S2/R2) of the second phase value to the second roughness value.
