ABSTRACT:
For a liquid crystal display apparatus, an orientating film of an electrode substrate including more signal electrodes than scanning electrodes in a predetermined range receives a uniaxial orientation treatment parallelly or almost parallelly to a lengthwise direction of the signal electrodes. Besides, an orientating film of an electrode substrate including the scanning electrodes receives a uniaxial orientation treatment perpendicularly or almost perpendicularly to a lengthwise direction of the scanning electrodes. The electrode substrates are combined so that the directions of the uniaxial orientation treatment of the orientation films become parallel to each other. This enables growth of a smectic layer to be less frequently hindered by differences in level caused by the electrodes. Thus a uniform C2U orientation can be obtained easily. Consequently, the liquid crystal display apparatus realizes a uniform orientational state with no defects and uniform and high-contrast display properties.
