Abstract

The objective is to provide a stereoscopic display device that is capable of preventing a malfunction of the touch panel while maintaining 3D capability. The device includes: a display panel (); a switch liquid crystal panel (); a touch panel (); a driving circuit (); and an RC circuit (). The switch liquid crystal panel () is located on the front side of the display panel () and is capable of forming a parallax barrier (). The touch panel () is located on the front side of the switch liquid crystal panel (). The driving circuit () drives the switch liquid crystal panel () to form the parallax barrier (). The RC circuit () is located between the switch liquid crystal panel () and the driving circuit (). The driving circuit () drives the switch liquid crystal panel () using a voltage with an effective value of 3 volts or more.
