Abstract:
1. A view angle controlling liquid crystal display device, comprising: a first panel part that has a first group of electrodes that includes a pixel electrode and a common electrode to generate a first vertical electric field, and a first liquid crystal layer driven by the first vertical electric field; and a second panel part deposited on the first panel part that has a second group of electrodes that includes a first electrode and a second electrode to generate a second vertical electric field, and a second liquid crystal layer driven to have a tilt angle from 10° to 80° by the second vertical electric field, and wherein the second panel part includes an ECB mode panel, wherein the first panel part includes: a first substrate; a first alignment layer formed to cover the pixel electrode formed on the first substrate; a second substrate arranged to face the first substrate that places the first liquid crystal layer in between; and a second alignment layer that covers the common electrode formed on a lower part of the second substrate and that is formed to have 90° rubbing direction against a rubbing direction of the first alignment layer, wherein a long axis of the second liquid crystal layer is arranged in parallel with the second substrate under an inactivated condition, and wherein the long axis of the second liquid crystal layer is arranged to have the tilt angle under an activated condition.
