ABSTRACT:
A liquid crystal display device and method of forming a liquid crystal display device are disclosed. The device having a plurality of pixel electrodes for transmitting light, includes a first panel including an activation region for selectively activating the plurality of pixel electrodes, a first orientation layer formed on the activation region, and a light shielding pattern formed on the first orientation layer; a second panel including a second orientation layer; and a liquid crystal formed between the first and second panels. The device allows proper formation of microgrooves in the entire first orientation layer, for enhancing orientation of liquid crystal molecules, increasing contrast ratio and improving picture quality of the device.
