Display device including touch panel and parallax barrier sharing single board
First Claim
1. A display device comprising:
- a display panel having a display surface;
a mutual capacitance sensing touch panel provided on a display surface side of the display panel; and
a parallax barrier configured to enable three-dimensional display, wherein;
the touch panel and the parallax barrier commonly share a single board as a common component;
the single board includes at least one pair of electrodes which are electrically separated from each other, wherein each of the at least one pair of electrodes is a comb-shaped electrode; and
the at least one pair of electrodes are configured to operate both of the touch panel and the parallax barrier.

Abstract
A display device includes a touch panel and displays stereoscopic images with reducing its thickness and weight. The display device includes a liquid crystal display panel 20, a switching liquid crystal panel 30 and a touch panel 50. The switching liquid crystal panel 30 is provided on a display surface side of the display panel 20 and switches a display mode between two-dimensional display and three-dimensional display. The touch panel 50 is provided on the display surface side of the display panel 20. The touch panel 50 and the switching liquid crystal panel 30 commonly include one common board 32 and are configured as one component. A touch panel transparent electrode 51 and a switching liquid crystal panel transparent electrode 33 are provided on the common board 32. The switching liquid crystal panel transparent electrode 33 applies a voltage to liquid crystals of the switching liquid crystal panel 30.
