Abstract
The stereoscopic display device has a display panel, a barrier liquid crystal panel disposed on the display panel, and a driving circuit for driving the display panel and the barrier liquid crystal panel, in which the frame frequency of the display panel and the alternating frequency of the barrier liquid crystal panel are different, the barrier liquid crystal panel is driven by a driving voltage input from the driving circuit, the driving circuit has an inverter circuit for outputting the driving voltage, independently controls a p-type transistor and an n-type transistor in the inverter circuit, and has time periods in which both the p-type transistor and the n-type transistor are turned off when the driving voltage is switched from a high level to a low level or a low level to a high level.
