A fabrication method for a liquid crystal display. A pair of substrates is provided. An alignment layer is formed on the respective substrates. An energy beam is irradiated on a predetermined area of at least one of the alignment layers. The alignment layer is rubbed to form a first pretilt-angle area in the predetermined area exposed to the energy beam, and a second pretilt-angle area not exposed to the energy beam. The pair of substrates are bonded with a preset gap therebetween, and a liquid crystal layer is inserted between the substrates. The liquid crystals corresponding to the first pretilt angle area have a first pretilt angle of &#x3b8;, while those corresponding to the second pretilt angle area have a second pretilt angle of &#x3b8;.

Fabrication method for liquid crystal display

A method of forming a transflective display device having a single cell gap in which a liquid crystal molecule has at least two pretilt angles. A transparent electrode is formed on the inner surface of the lower substrate, and a reflective electrode is formed on a portion of the transparent electrode. Thus, creating a reflective region over the reflective electrode, and a transmissive region over the transparent electrode which is not covered by the reflective electrode. Using a photo-alignment process to form at least two alignment domains on each of the two alignment layers sandwiching a liquid crystal layer, the pretilt angle of the liquid crystal molecule in the reflective region is different from the pretilt angle of the liquid crystal molecule in the transmissive region, the reflective region and the transmissive region have the same phase retardation, and the light path passing through the reflective region is twice the light path passing through the transmissive region.

Transflective display device with different pretilt angles and fabrication method for thereof

A transflective display device having a single cell gap in which a liquid crystal molecule has at least two pretilt angles. A transparent electrode is formed on the inner surface of the lower substrate, and a reflective electrode is formed on a portion of the transparent electrode, such that a reflective region is over the reflective electrode and a transmissive region is over the transparent electrode, which is not covered by the reflective electrode. The pretilt angle of the liquid crystal molecule in the reflective region is different from the pretilt angle of the liquid crystal molecule in the transmissive region, the reflective region and the transmissive region have the same phase retardation, and the light path through the reflective region is twice the light path passing through the transmissive region.

A wide-viewing angle display device serves as a multi-domain vertical alignment (MVA) mode liquid crystal display (LCD) device or an in-plane switching (IPS) mode liquid crystal display (LCD) device. A plurality of protrusions is formed on the inner surface of the glass substrate, and an electrode array is formed on the tops of the protrusions. Thus, the electrodes are suspended in the liquid crystal cell gap, and a transverse electrical field is generated by the electrodes to drive the liquid crystal molecules.
