摘要:
A liquid crystal display device is characterized by comprising first and second substrates on a surface of which electrodes are formed, a liquid crystal material with ferroelectricity or antiferroelectricity interposed between the first and second electrodes, and an orientation film and disposed between the electrode or electrodes formed on the surface of said first and/or second substrate whose surface has been subjected to a process which gives optically uniaxial orientation to the liquid crystal material, wherein said orientation film has a pretilt angle of 1.6 to 3.1 degree with respect to a nematic liquid crystal. Further, a value of a polar term of surface tension on the surface of the orientation film ranges from 11 to 15 dyne/cm.

In an active matrix semiconductor display device in which pixel TFTs and driver circuit TFT are formed on the same substrate in an integral manner, the cell gap is controlled by gap retaining members that are disposed between a pixel area and driver circuit areas. This makes it possible to provide a uniform cell thickness profile over the entire semiconductor display device. Further, since conventional grainy spacers are not used, stress is not imposed on the driver circuit TFTs when a TFT substrate and an opposed substrate are bonded together. This prevents the driver circuit TFTs from being damaged.

In an active matrix type liquid crystal display device, a plurality of pixels connected to thin film transistors (TFTs) are arranged in an active matrix form in a pixel portion, and driven by a driver circuit portion. The pixel portion and the driver circuit portion are formed on one of a pair of insulating substrates. A liquid crystal material is interposed between the insulating substrates. An black matrix material made of an organic resin is formed over the one insulating substrate in which the driver circuit portion has been formed. An flat film is formed on the black matrix material.

摘要:
In a liquid crystal device using a ferroelectric liquid crystal, in the case that a liquid crystal material is injected in a space between a pair of substrates (at least one of the substrates having an alignment film), a liquid crystal mixture of a liquid crystal material and an uncured resin material having a hydrophilicity is injected in the space from an injection inlet formed between the substrates. By the above process, the uncured resin material is remained in the vicinity of the injection inlet, and the space is filled with the liquid crystal material. Subsequently, the resin material is cured to seal the injection inlet. Further, a space between a pair of the substrates is filled with a mixture of the liquid crystal material, the uncured resin material and spacer particles, the liquid crystal material is oriented, the uncured resin material is precipitated from the mixture and cured, and the liquid crystal material and the spacer particles are removed. Subsequently, the liquid crystal material (or a mixture of the liquid crystal material and the uncured resin material) is again injected in the space, the liquid crystal material is oriented, and the uncured resin material is precipitated to be cured.

摘要:
An EL display device capable of reducing an average film resistance of an anode in an EL device as well as displaying an image with high definition, and electrical equipment including such an EL display device are provided. A light-shielding metal film (109) is provided on an anode (108) so as to conceal gaps between the pixels. Thus, an average film resistance of the anode (108) in the EL device is reduced. Furthermore, light leakage from the gaps between the pixels can be prevented, resulting in an image display with high definition.
