Stereoscopic image display including 3D filter with improved voltage driving

摘要

3D filter driving voltages can be stably supplied to the 3D filter via flexible printed circuit for distributing first to third voltages of the 3D filter driving voltage, even if electrodes of the 3D filter are shorted, by supplying the 3D filter driving voltages to the 3D filter in a distributed fashion.
