Benefits of technology
This patent is about a liquid crystal display device that helps to keep the liquid crystals in the display aligned properly. This improves the quality of the display and can help to make it more stable and reliable.
Problems solved by technology
It is noted, however, there is a limit in improving the display quality of an LCD device using a PI-based alignment layer including a polymer having a photo-reactive group.
For example, a PI-based alignment layer including a photo-reactive group has low thermal stability and low hardness, and thus, may cause various problems such as alignment instability and image sticking due to a weak alignment force.

Embodiment Construction
[0035]In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments.
[0036]In the accompanying figures, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and descriptive purposes. Also, like reference numerals denote like elements.
[0037]When an element or layer is referred to as being “on,”“connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, an element or layer is re...

Abstract
A liquid crystal display device including: a first substrate including a first base substrate, a first field-generating electrode disposed on the first base substrate, and a second field-generating electrode disposed on the first field-generating electrode; a second substrate facing the first base substrate and disposed spaced apart from the first substrate; a liquid crystal layer including liquid crystals, in which an electric field is formed by the first field-generating electrode and the second field-generating electrode, being disposed between the first substrate and the second substrate and contacting the second field-generating electrode; and a plurality of first projections disposed between the second field-generating electrode and the liquid crystal layer.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit of Korean Patent Application No. 10-2016-0016367, filed on Feb. 12, 2016, which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND[0002]Field[0003]Exemplary embodiments relate to a liquid crystal display device and a method of manufacturing the liquid crystal display device.[0004]Discussion of the Background[0005]A liquid crystal display (LCD) device, which is one of the most widely-used display devices, includes two substrates on which field-generating electrodes such as pixel electrodes and a common electrode are formed and a liquid crystal layer which is disposed between the two substrates.[0006]The LCD device generates an electric field by applying a voltage to the field-generating electrodes and determines an alignment direction of liquid crystals in the liquid crystal layer. The LCD device displays an image by controlling the polarization ...
