Abstract

The invention provides a liquid crystal display and a method for manufacturing the same. The liquid crystal display comprises an upper substrate, a lower substrate and a liquid crystal layer, wherein the liquid crystal layer is clamped between the upper substrate and the lower substrate. A plurality of pixel structures are formed on the lower substrate, and each pixel structure comprises a common electrode, a primary pixel electrode, a secondary pixel electrode, a first switching device and a second switching device, wherein the common electrode is formed on the lower substrate and comprises a primary pixel common electrode and a secondary pixel common electrode, the primary pixel electrode corresponds to the primary pixel common electrode, the secondary pixel electrode corresponds to the secondary pixel common electrode, the first switching device is connected with the primary pixel electrode and a data line, and the second switching device is connected with the secondary pixel electrode and a data line. The production technology of the liquid crystal display with a controllable view angle can be simplified, and production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays (TFT-LCDs), in particular to a liquid crystal display and a manufacturing method thereof. Background technique [0002] In recent years, liquid crystal display technology has developed very rapidly, and many methods have been proposed to solve the liquid crystal viewing angle problem, such as in-plane switching mode (IPS, In Plane Switching) and fringe field switching mode (FFS, Fringe Field Switching). Displays with a single viewing angle mode can no longer meet the needs of users. Users hope that LCD displays should have the ability to switch between wide and narrow viewing angle modes: when users need to share information, turn on the wide viewing angle mode; when users want to When you want to protect the displayed information, you can choose to use the narrow viewing angle mode. Therefore, a viewing angle controllable liquid crystal display appears in the prior art, and the l...
