The present invention discloses an LCD panel and a method for fabricating the same. More specifically, the LCD panel includes first and second substrates, a photo-hardening sealant between the first and second substrates, a plurality of metal lines on the first substrate, wherein the metal lines are formed of a transparent conductive film at least at portions where the metal lines cross one another, and a liquid crystal layer between the first and second substrates. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Liquid crystal display panel and method for fabricating the same

A method is disclosed for controlling a pretilt angle direction for a liquid crystal cell comprising the steps of first setting the magnitude of pretilt angle and a plurality of pretilt angle directions in an alignment layer. This first step is achieved by irradiating linearly the alignment layer with polarized or unpolarized UV light. One of the plurality of pretilt angle directions is then selected by exposing the alignment layer to UV light a second time.

Method for controlling pretilt angle direction in a liquid crystal cell

A liquid crystal cell having a first substrate with a rubbed layer provided thereon, a second substrate with a photo-aligned layer provided thereon, and a liquid crystal material provided between the substrates.

Liquid crystal cell and method of manufacture

A method for fabricating a liquid crystal cell and related device includes providing an alignment layer of a light sensitive material on a substrate; and exposing the alignment layer to unpolarized or partially polarized light, to provide pretilt for the molecules of the alignment layer.

Method for fabricating a liquid crystal cell

A multi-domain liquid crystal display device includes first and second substrates facing each other, the first substrate including a thin film transistor; a plurality of gate bus lines arranged in a first direction on the first substrate and a plurality of data bus lines arranged in a second direction on the first substrate to define a plurality of unit pixel region, the pixel region including a plurality of unit domain in a shape of stripe; a liquid crystal layer between the first and second substrates; a pair of driving electrodes driving the liquid crystal layer; and a plurality of black matrix on the region of the plurality of gate and data bus lines, the thin film transistor and on the boundaries of the adjacent unit domain in the unit pixel region, the widths of the plurality of black matrix being different one another.

Pretilt angle direction in a liquid crystal cell

A method is disclosed for controlling a pretilt angle direction for a liquid crystal cell comprising the steps of first setting the magnitude of pretilt angle and a plurality of pretilt angle directions in an alignment layer. This first step is achieved by irradiating the alignment layer with linearly polarized or unpolarized UV light. One of the plurality of pretilt angle directions is then selected by exposing the alignment layer to UV light a second time.

A LC cell is manufactured by the method including the steps of: rubbing a first alignment layer coating a first substrate, such that the first alignment layer has a first pretilt angle associated therewith; exposing said second alignment layer coating a first substrate to light such that said second alignment layer has at least one second pretilt angle associated therewith; and providing a liquid crystal material between said first and second substrates. The materials for the first and second alignment layers include a polyimide and a polysiloxane based material.
