Patent abstract

Disclosed is a transcription plate for forming orientation layer by coating printed orientation agent onto a substrate. The transcription plate comprises a base film and photosensitive resin plate, such as an APR layer, wherein a number of dots are arranged on the photosensitive resin plate in a regular fashion, and an arrangement of outer dots disposed outside of an active area of the transcription plate is denser than that of inner dots disposed within an active area of the transcription plate. The transcription plate enables the thickness of the orientation layer along the edge outside of the active layer of the transcription plate to be formed with the uniform thickness. Therefore, a uniform image property can be obtained by uniform rubbing. Further, because such phenomenon as conglomeration of the orientation agent does not occur, non-uniformity of cell gaps, which is caused by the superposition on the sealing line, can be solved.
