Abstract
The disclosure provides a viewing angle control module including a first liquid crystal panel, a first polarizer, a second polarizer, and a phase retarder. The first liquid crystal panel includes a first substrate, a second substrate, a first alignment layer, a second alignment layer, a first liquid crystal layer, a first electrode layer, and a second electrode layer. A second alignment direction of the second alignment layer is antiparallel to a first alignment direction of the first alignment layer. The first electrode layer has multiple electrode patterns arranged at intervals along a first direction and extending along a second direction. A first absorption axis of the first polarizer is perpendicular to a second absorption axis of the second polarizer. An included angle between the first absorption axis and the first alignment direction is 45 degrees. A display apparatus including the viewing angle control module is also provided.
