DISPLAY PANEL AND DISPLAY DEVICE

摘要

The invention discloses a display panel which includes a liquid crystal cell; a first polarizer, arranged on a light inputting side of the liquid crystal cell; and a second polarizer, a polarization direction of which is perpendicular to a polarization direction of the first polarizer, wherein the second polarizer is detachably arranged on a light outputting side of the liquid crystal cell and is able to cover a valid display region of the display panel. The invention also discloses a display device which includes above display panel and polarized glasses. When there are no confidential files, the second polarizer covers a valid display region of display panel; when there are confidential files to be processed, the second polarizer is removed from the valid display region of display panel. Therefore, it is possible to effectively improve the availability of the display panel and the display device having said display panel.
