Title:
DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2011227225
Kind Code:
A
Abstract:

To provide a display device having display quality improved by suppressing an anomalous change in voltage of a display electrode caused by parasitic capacitance; and a method for driving the same.

The display device comprises: a first pixel circuit having a first switching element and a first display electrode; a second pixel circuit having a second switching element and a second display electrode; and display control voltage supply means which provides the first and second display electrodes with a display control voltage through the first and second switching elements. During a first writing period, the display control voltage supply means switches on the first and second display switching elements to provide the first and second display electrodes with the display control voltage corresponding to data displayed on the first pixel circuit, and, during a second writing period, it provides the second display electrode with the display control voltage corresponding to data displayed on the second pixel circuit while keeping the first and second display switching elements switched on.
