Patent ID: 8659586

Claim:
A stereoscopic image display device comprising: a display panel and a LC barrier panel placed upward the display panel; the display panel includes first column electrodes and second column electrodes, the first column electrodes can display an image for right eye and the second column electrodes can display an image for left eye, the first column electrodes and the second column electrodes are alternately formed; the LC barrier panel includes a substrate, a counter substrate, a sealant for bonding the substrate and the counter substrate with a predetermined gap, and a liquid crystal layer filled in the predetermined gap; first barrier pixels and second barrier pixels are alternately arranged in a vertical direction on the substrate; third barrier pixels and the first barrier pixels are alternately arranged in a horizontal direction on the substrate; a counter electrode formed on the counter substrate, the counter electrode is opposed to all of the first barrier pixels, the second barrier pixels and the third barrier pixels; when the LC barrier panel performs vertical stripe barrier display, a third signal supplied to the third barrier pixels and a counter signal supplied to the counter electrode are the same drive signal, and a first signal supplied to the first barrier pixels makes an effective voltage for the liquid crystal layer between the counter electrode and the first barrier pixels, and a second signal supplied to the second barrier pixels makes an effective voltage for the liquid crystal layer between the counter electrode and the second barrier pixels; and when the LC barrier panel performs horizontal stripe barrier display, the second signal and the counter signal are the same drive signal, and the first signal makes an effective voltage for the liquid crystal layer between the counter electrode and the first barrier pixels, and the third signal makes an effective voltage for the liquid crystal layer between the counter electrode and the third barrier pixels.
