摘要： PROBLEM TO BE SOLVED: To provide a process for producing color filters with which the curling of the base film itself is prevented even when the formation of the somewhat thin base film and the clean and sure transfer of a color ink layer 2 onto a base to be colored is made possible. SOLUTION: A color film sheet 10 is formed by successively laminating a stress relief layer 6, a photothermal conversion layer 4 and the color ink layer 2 in this order on the base film 3. The sheet 10 is provided with the stress relief layer 6, by which the swelling of the solvent component incorporated into the photothermal conversion layer 4 or the color ink layer 2 on the surface of the base film 3 at the time of storage is averted and the deformation of the color film sheet 10 is prevented.

摘要： PURPOSE:To stick substrates for LCDs is manner as to allow the control of a gap with high accuracy and easy practicable use by successively irradiating an adhesive applied region with the light of an illuminating member under pressurization by rolling of a press roller. CONSTITUTION:The photosetting adhesive 1 applied between the glass substrates 2 and 3 is cured while the adhesive is held pressurized by the press roller 4. There is no longer the possibility that a pressure is generated after the pressurization. The two glass substrates 2, 3 can be adhered by maintaining the prescribed gap if the region coated with the adhesive 1 is pressurized and photoirradiated while the press roller 4 and optical fibers 5, 6 are kept moved. The fluctuation in the gap occurring in the reaction of the photosetting adhesive is averted in this way and since the photoirradiation is executed simultaneously with the pressurization, the gap control with the high accuracy is possible. In addition, the operations are executed by the inexpensive device combining the press roller 4 and the optical fibers 5, 6 and, therefore, the practicable use is easy.

摘要： PURPOSE:To more strictly control quality and to produce the high-grade element at a good yield by measuring the double refractive phase differences before and after the rubbing treatment of the oriented films formed on substrates and deciding whether the difference between the two measured values is within a permissible level or not. CONSTITUTION:Transparent electrodes are patterned on the glass substrates and the oriented films are applied and formed thereon. The double refractive phase difference of the oriented films is measured as an initial value before the rubbing treatment. The double refractive phase difference of the oriented films subjected to the rubbing treatment is then measured and whether the difference from the initial value is within the permissible level or not is decided. The substrates are sent as non-defective articles to an assembly stage when the difference is within the permissible level. The substrates are subjected as defective articles to the correction of the rubbing treatment if the difference is off the permissible level. The high-grade liquid crystal display element is produced at the good yield by executing the strict quality control in such a manner.

摘要： PURPOSE:To execute real time process control and to improve the yield of products by detecting the generation of abnormality causing orientation defects due to the change in torque of a driving motor. CONSTITUTION:A cylindrical rubbing roll 1 constituted of winding a rubbing material around its surface is driven by the driving motor and rotated at high speed and the rubbing material 2 rubs the orientation film to execute orientation processing. In order to apply the signal processing on the change of torque in the motor 3, the voltage drop due to current flowing into a reference resistor 4 is detected and the torque signal passing a low pass filter 5 is amplified by an amplifier 6. When the amplified value of the torque signal is decided to be smaller than an allowable minimum value VL by a comparator 7, the motor 3 is immediately stopped by a control signal generated from an originator 8. Thus, the process control capable of quickly process the generation of abnormality at the time of rubbing, and generating no production loss can be attained.
