    Abstract: An image signature creating method includes: creating a map by partitioning a still image using rings defined by concentric circles radially spaced apart from each other by a predetermined interval and radial lines circumferentially spaced apart from each other by a predetermined angle, the center of the still image being that of the concentric circles; and creating an image signature from the created map on the basis of distribution of pixels in regions defined by the rings and the radial lines. Accordingly, distribution of illegal contents is prevented and interrupted by search for and discrimination of a still image illegally deformed by a copying of or an intended attack on the still image.

    Abstract: A liquid crystal display with better visibility and transmittance. The liquid crystal display includes a first plate having a first field-generating electrode, disposed in a pixel area on an insulating substrate, comprising a plurality of sub-electrodes which are separated from each other by a predetermined distance and arranged parallel to each other, and a connecting electrode electrically connecting the sub-electrodes. An alignment film that is rubbed in a first direction covers a first field-generating electrode and an alignment film that is rubbed in a second direction covers a second field-generating electrode to achieve a predetermined orientation of the liquid crystals when no field is applied and more uniform rotation of the liquid crystal molecules when a field is applied.
