A liquid crystal display panel includes a first substrate, a second substrate, a first alignment layer, a second alignment layer and a liquid crystal layer. The second substrate faces the first substrate. The liquid crystal layer is disposed between the first alignment layer and the second alignment layer. The first alignment layer and the second alignment layer each include a polyimide compound polymerized by cyclobutane-1,2,3,4-tetracarboxylic dianhydride and cyclobutane-1,2,3,4-tetracarboxylic dianhydride derivative.

A novel cable television (CATV) signal tuning method, which is capable of reducing the time taken to tune CATV signals transmitted via a cable, comprises (a) determining, in response to a mode determination signal, one of harmonical related carriers (HRC), interval related carrier (IRC) and standard (STD) transmission modes as a definitive transmission mode for a plurality of channels, to thereby produce mode information of the definitive transmission mode; (b) storing the mode information; and (c) fine-tuning, in response to a channel selection signal, a CATV signal from a selected channel based on the definitive transmission mode represented by the stored mode information.
