POLARIZED TYPE VIEWING ANGLE CONTROL DEVICE, POLARIZED TYPE VIEWING ANGLE CONTROL DISPLAY APPARATUS AND POLARIZED TYPE VIEWING ANGLE CONTROL LIGHT SOURCE MODULE

摘要

A polarized type viewing angle control device including a first polarizer, a second polarizer, a first O-plate compensation film, and a second O-plate compensation film is provided. The first polarizer has a first transmission axis. The second polarizer has a second transmission axis parallel to the first transmission axis. The first and second O-plate compensation films are located between the first and second polarizers and respectively have a first optical axis and a second optical axis. An orthogonal projection of the first optical axis on the first polarizer and an orthogonal projection of the second optical axis on the second polarizer are parallel or perpendicular to the first transmission axis and the second transmission axis. The second optical axis and the first optical axis have opposite inclination directions. A polarized type viewing angle control display device and a polarized type viewing angle control light source module are also provided.
