A switchable 2D/3D display includes a liquid crystal display (LCD) panel and a switchable barrier. The LCD panel includes a first substrate, a second substrate, a first twisted nematic (TN) liquid crystal layer, a first wide-view film set including a first wide-view film and a second wide-view film, and a first polarizer set. The first polarizer set includes a first polarizer and a second polarizer. Transmission axes of the first and second polarizers are substantially perpendicular to each other. The switchable barrier includes a third substrate, a fourth substrate, a second TN liquid crystal layer, a second wide-view film set including a third wide-view film and a fourth wide-view film, and a second polarizer set. The second polarizer set includes a third polarizer and a fourth polarizer. Transmission axes of the third and fourth polarizers are substantially perpendicular to each other.
