Abstract: In a method and apparatus of aligning liquid crystal, a first ion beam is formed. The first ion beam is transformed into a second ion beam having transformed cross-section. The second ion beam advances toward a thin film including carbon-carbon double bond. The second ion beam forms a first angle with respect to the thin film. The second ion beam is transformed into an atomic beam. The atomic beam is irradiated onto the thin film to break the carbon-carbon double bond. The carbon-carbon double bond is broken to form a polarized functional group for aligning a liquid crystal molecule.

Abstract: A liquid-crystal droplet accreting onto an alignment layer spreads in a wet state but the diameter of the liquid-crystal droplet does not become greater than a certain size. When the diameter of the liquid-crystal droplet in that state is represented by Dmax and is defined as the largest wet-spread diameter of the liquid-crystal droplet, the liquid-crystal droplet is dropped on a substrate such that the spacing I between the drop center C of the liquid-crystal droplet and the inner edge of the sealant (the edge of the sealant close to a display area) is greater than half of the largest wet-spread diameter Dmax of the liquid-crystal droplet.

Abstract: A method of forming a liquid crystal display device includes forming an amorphous silicon layer over a substrate and forming a light reflecting layer only over a first portion of the amorphous silicon layer. The amorphous silicon layer is then irradiated with a laser to convert it to a polysilicon layer. The light reflecting layer partially reflects the light away from the first portion of the amorphous silicon layer such that a first portion of the polysilicon layer has a first polysilicon grain size and a second portion of the polysilicon layer has a second polysilicon grain size, which is larger than the first polysilicon grain size. A first plurality of thin film transistors having reduced leakage current characteristics may then be formed from the first portion of the polysilicon layer.

Abstract: A transflective liquid crystal display panel, in which at least one of a pixel electrode substrate and a counter electrode substrate is provided with a protruding portion so that the thickness of a liquid crystal layer in a reflective region is smaller than that in a transmissive region, wherein a light-blocking section for shading a defective orientation domain formed by an insufficiently-rubbed portion around the protruding portion is formed simultaneously with, and using the same material as, another element such as a storage capacitor electrode section, a signal line or a scanning line. Thus, the decrease in the display quality due to the defective orientation domain can be suppressed without adding to the production process.

Abstract: A color filter (30) includes a black matrix (33), and the black matrix has a first antireflection layer (331) and a second antireflection layer (332) on the first antireflection layer. Each antireflection layer includes a first antireflection film (3311, 3321) having a first refraction index, and a second antireflection film (3312, 3322) having a second refraction index which is different to the first refraction index. Because of so-called destructive interference of outside source light beams reflected from various interfaces defined by the first and second antireflection films, net reflection of the light beams by the black matrix back to an outside of the color filter is minimal. For similar reasons, net reflection of internal source light beams by the black matrix back to an inside of the color filter is minimal. As a result, visibility of a liquid crystal display device (300) employing the color filter is improved.
