Abstract: PURPOSE: To embody a partial change of the orientation direction on a substrate by irradiating a high-polymer oriented film formed on a substrate with linearly polarized UV rays, rotating the polarization direction and irradiating the high-polymer oriented film diagonally with the UV rays. CONSTITUTION: This device for controlling the orientation of liquid crystals consists of a UV light source 6 combined with a mercury lamp 2 and a linear polarization element 4, such as Wollaston prism, an irradiation light inclining means 12 for inclining the UV light linearly polarized from the light source 6 relatively at an arbitrary angle with the normal of the substrate 10 and a polarization direction changing means 14 capable of irradiating the substrate in the polarization direction arbitrarily to the reference direction of the substrate. The high-polymer oriented film is formed on the substrate 10, such as glass substrate, and is irradiated with the UV rays of the wavelength absorbed therein with a linearly polarized light state; thereafter, the irradiation light inclining means 12 and the polarization direction changing means 14 rotate/incline the substrate 10 with respect to the fixed light source 6 and rotate the polarization direction at 90 deg. with the polarized light for irradiating the orientation. In addition, these means incline the irradiation direction within the perpendicular plane inclusive of the polarization direction with respect to the substrate 10 and irradiate again the substrate 10.

Abstract: PURPOSE: To provide a liquid crystal display device which has excellent visual characteristics with a simple process. CONSTITUTION: A color filter board and a TFT board are nearly evenly coated with polyimide so as to form an orientation film (S1) Rubbing is performed to each board (S2). Each board, to which rubbing is performed, is irradiated with the ultraviolet rays of the linear polarization polarized in the direction along the rubbing direction (S3). A side chain of polyimide in the direction along the linear polarization is thereby cut, and a side chain of the polyimide related to the only pre-tilt angle of liquid crystal can be cut so as to change the pre-tilt angle of the liquid crystal. Each board are arranged opposite to each other with the predetermined cell gap, and periphery is sealed, and liquid crystal is filled between both the boards (S4, S5), and a polarizing plate is attached to the outer surface so as to finish the liquid crystal display device.

Abstract: PURPOSE: To provide a wide view angle liquid crystal display device with which problems such as the complication of processes, the change of electric characteristics and the instability of oriented state are canceled. CONSTITUTION: A soluble polyimide solution a prepared by dissolving soluble polyimide, of which the pretilt angle is changed by a burning temperature, in a solvent and applied to a color filter board 12 and a TFT substrate 14. The lower half of picture elements 28 on the color filter substrate 12 and the upper half of picture elements 28 on the TFT substrate 14 are heated and dried earlier than the other parts for prescribed time by irradiating them with laser beams, and the remaining parts are naturally dried. The pretilt angle of molecule 16A of liquid crystal 16 in contact with the heated and dried part gets small but the pretilt angle of molecule 16A in contact with the naturally dried part gets large and the direction of satisfactory view angle is inverted for the upper half and lower half of picture elements 28 so that the wide view angle can be obtained.
