Abstract: A continuous domain vertical alignment liquid crystal display (2) has a first substrate (21), a second substrate (22), and liquid crystal molecules (26) interposed between the substrates. A plurality of curved slits (211) and a plurality of curved protrusions (221) are disposed at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules are inclined to be oriented parallel to the substrates. In addition, the curved slits and the curved protrusions affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.

A plurality of curved first protrusions (211) and a plurality of curved second protrusions (221) are disposed at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules tend to be oriented parallel to the substrates. In addition, the curved protrusions affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.

Abstract: A photo-mask process includes the steps of: spreading a film of photo resist on a carrier (30, 50), exposing the photo resist using a mask with a predefined pattern, developing the photo resist to obtain a photo resist layer (36, 60) with the predefined pattern, depositing a layer of predetermined material on the photo resist layer and the carrier, and removing the photo resist layer and the layer of predetermined material thereon.

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.

Abstract: An IPS (in-plane switching) liquid crystal display (2) has a first substrate (23), a second substrate (24) opposite to the first substrate, a liquid crystal layer disposed between the two substrates, a plurality of common electrodes (25) and pixel electrodes (26) disposed on the second substrate, and a plurality of spacers (29) disposed on the common electrodes and the pixel electrodes. The spacers are electrically conductive. The liquid crystal layer, together with the electric field generators comprising the electrodes and the spacers connected with them, cooperatively form a “functionally unified” configuration. Accordingly, liquid crystal molecules (27) in the liquid crystal layer are in a strong electric field having a highly uniform direction. The strong electric field enables the IPS type liquid crystal display to operate on a lower driving voltage, and/or to provide more space between the electrodes to yield a higher aperture ratio.
