Problems solved by technology

In these modes, vertically aligned liquid crystals have negative dielectric anisotropy, resulting in higher rotational viscosity compared to liquid crystals with positive dielectric anisotropy, which results in slow response times
In addition vertical alignment of liquid crystals is not easy and can only be achieved by one of several rather complicated processes

Embodiment Construction

[0027] Some embodiments of the invention will be described in detail using appropriate exemplary figures. Reference numerals are added to each component of the drawings, and it should be noted that the same components are denoted by the same reference numerals whenever possible in other drawings. Also, in explaining the embodiments of the present invention, if a detailed description of a related known configuration or function obscures the gist of the present invention, the detailed description will be omitted.

[0028] In addition, the terms “first”, “second”, “A”, “B”, “(a)”, “(b)” may be used in describing components of the embodiments of the present invention. These terms are only used to distinguish one component from another, and they do not limit the elements, sequence or sequence of the corresponding components. It should be understood that when a component is "connected," "coupled" or "connected" to another component, the component may be directly connected, coupled ...

Abstract

The present invention discloses a liquid crystal display of the IPS type, which has improved characteristics in terms of stability of liquid crystal element, response time, threshold voltage, and driving voltage due to conferring a pretilt angle to a liquid crystal layer, and method for preparation thereof.

Description

[0001] The present invention relates to a liquid crystal display for producing images and a method of manufacturing the same. technical field [0002] The present invention relates to a liquid crystal display for producing images and a method of manufacturing the same. Background technique [0003] Liquid crystal displays project images by controlling light transmittance of liquid crystals with an applied electric field, and they are classified into vertical electric field type and horizontal electric field type. [0004] In a horizontal electric field type liquid crystal display, a horizontal electric field applied between a pixel electrode and a common electrode disposed side by side on a lower substrate drives liquid crystal of a so-called in-plane switching (IPS) mode display. The horizontal electric field type display has an advantage of a wide viewing angle due to the rotation of a liquid crystal director on a flat substrate, but it disadvantageously exhibits poor tran...
