Abstract: PROBLEM TO BE SOLVED: To shift an OCB cell from a spray orientation state to a bend orientation state in a short time by applying a voltage which is higher than an electric field needed to continue bend orientation between a display electrode (pixel electrode) and a common electrode. SOLUTION: When the power source is turned on, a power-on reset signal is outputted for t1 seconds, and a gate pulse which is about 20-20V similar to an ordinary gate pulse, but has a period much wider than that in ordinary gate timing is outputted to a gate line in the t1 seconds. The gate-on time of this driving method is set long to several msec - several sec. Consequently, the bend orientation as a nucleus is formed between the gate electrode and common electrode. Further, the whole pixel shifts to the bend orientation with the electric field applied between the display electrode and common electrode. As a higher and higher voltage is applied between the display electrode and common electrode, the shift to the bend orientation is faster and faster.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in the visual sensation characteristics of a screen, each as reversal development at a vertical visual field angle, by determining the min. wavelength λ among the wavelengths of the light relating to colors, the min. value V1 of a driving voltage and the optical phase difference R(V1 ) at this voltage so as to satisfy a specific relation. SOLUTION: The optimum value of the optical phase difference R(V1 ) relating to the respective colors of R(red), G(green), B(blue) is determined, by which the optically rotatory power of liquid crystals for B(blue) wavelength is prevented. The R(V1 ) is the absolute value of retardation before correction by a phase compensation film at the driving voltage V. on a low side. Namely, the occurrence of the optically rotatory power of the liquid crystals for the B(blue) wavelength is prevented by the optimization of the value of R(V1 )/λ. The term 'optimization' signifies to satisfy the relation R(V1 )/λ=

Abstract: PROBLEM TO BE SOLVED: To provide a control system which applies a voltage to a liquid crystal layer to have short-time transition to bend orientation for a liquid crystal display device which uses the liquid crystal layer with the bend orientation. SOLUTION: While the potential difference VG-VS between a gate electrode and a signal electrode is held above 10V, a potential difference of >=10V is applied continuously or intermittently between the signal electrode and a counter electrode. When the voltage is applied intermittently, an ON time for which the potential difference is applied between the signal electrode and counter electrode is preferably longer than a time wherein part of the liquid crystal layer substantially begins to change into spray orientation as a 2nd stage and an OFF time for which the potential difference is not applied between the signal electrode and counter electrode is desirably longer than a time needed for a return of the liquid crystal area of the spray orientation as the 2nd stage to the state before the potential is applied.
