Abstract

A display panel includes a first substrate and a second substrate assembled together with a sealant, and the resultant assembly encloses a display medium layer. An organic alignment layer and an inorganic alignment layer are disposed between the first substrate and the display medium layer. A first gap exists between the inorganic alignment layer and the sealant, and the organic alignment layer is located in the first gap. The inorganic alignment layer may contact the display medium layer, and the organic alignment layer may be in contact with the display medium layer in the first gap. A portion of the organic alignment layer may overlap the inorganic alignment layer. The inorganic alignment layer may be coated with a coating of hydrophobic molecules. The display panel may further include an opposite organic alignment layer and an opposite inorganic alignment layer between the second substrate and the display medium layer.
