Electrically-driven liquid crystal lens and stereoscopic display device using the same

Abstract

An electrically-driven liquid crystal lens wherein electric connection between finely split electrodes and signal lines used to apply signals to the split electrodes can be accomplished using a minimal number of masks and signals can be applied to the finely split electrodes without line resistance, and a stereoscopic display device using the same are disclosed. The liquid crystal lens includes first and second substrates arranged opposite each other and each defining a plurality of lens regions, a plurality of metal lines formed on the first substrate, a first insulating film formed on the first substrate, a plurality of first electrodes formed on the first insulating film in the respective lens regions to intersect the plurality of metal lines, a second insulating film formed on the first electrodes, a plurality of second electrodes formed on the second insulating film at positions alternating with the first electrodes, a first contact structure between the first electrodes and the metal lines using a transparent electrode pattern of the same layer as the second electrodes, a second contact structure between the second electrodes and the plurality of metal lines, a common electrode formed over the entire surface of the second substrate, and a liquid crystal layer filled between the first substrate and the second substrate.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2007-130926 filed on December 14, 2007, which is hereby incorporated by reference in its entirety as if fully set forth herein. technical field [0002] The present invention relates to a stereoscopic display device, and more particularly to an electrically driven liquid crystal lens, and a stereoscopic display device using the electrically driven liquid crystal lens, in which finely separated electrodes and users can be realized using a minimum number of masks. An electrical connection between signal lines that apply signals to separate electrodes, and wherein signals can be applied to finely divided electrodes without being affected by line resistance. Background technique [0003] At present, services for rapidly distributing information based on high-speed information communication networks have evolved from simple "listening" services such as current telephones to "audio" services based on digit...
