INFORMATION OUTPUT DEVICE
Document Type and Number:
Japanese Patent JPH0478819
Kind Code:
A
Abstract:
PURPOSE:To reduce the size and weight of the device by providing a liquid crystal electooptical device packaged with a liquid crystal driver IC for applying an electric signal to a liquid crystal on either of substrates facing each other between a photosensitive drum and a light source. CONSTITUTION:The liquid crystal electrooptical device which includes the liquid crystal exhibiting a ferroelectric property in a liquid crystal cell provided with a 1st substrate consisting of one piece of electrode consisting of a light transparent conductive material and leads on a light transparent substrate (for example, a 1st substrate having an SiO2 film of 1,000Angstrom thickness on soda lime glass of 1.1mm thickness) and a 2nd substrate consisting of plural pieces of electrodes consisting of a light transparent conductive material and leads on a light transparent substrate, includes the liquid crystal having an ester bond in the main skeleton and has means for arraying the liquid crystal compsn. in a specified direction is provided between the photosensitive drum and the light source. Electric circuit parts for driving this liquid crystal are packaged with the driver IC 9 for applying the electric signal to the liquid crystal on the 2nd substrate 6 constituting the liquid crystal cell and the output terminals of the IC 9 and the electrodes 8 on the substrate are connected electrically on the substrate, by which the size and weight over the entire part of the device are reduced.
