Patent ID: 8872990

Claim:
A display device comprising: a main panel configured to display an image; a switch panel located opposite the main panel for displaying a slit image serving as a parallax barrier to allow an image displayed on the main panel to be viewed stereoscopically; a first polarizer located closer to a viewed side of the main panel; a second polarizer located between the main panel and the switch panel; and a third polarizer located closer to a side of the switch panel opposite a side closer to the main panel, wherein the switch panel includes a pair of opposite substrates and a liquid crystal layer formed between the pair of substrates, each of the substrates has an alignment film on a side closer to the liquid crystal layer, the alignment films having been rubbed at different angles as viewed from a viewed side of the switch panel, a direction of rubbing for one of the alignment films located closer to the third polarizer is at an angle relative to an absorption axis of the third polarizer as viewed from the viewed side of the main panel such that a contrast ratio within a view range of left and right eyes is equal to or higher than a reference value, the contrast ratio being measured on a visual line for the switch panel corresponding to a transmission axis of the second polarizer.
