Disclosed are methods and compositions for the identification, characterization and inhibition of farnesyl protein transferases, enzymes involved in the farnesylation of various cellular proteins, including cancer related ras proteins such as p21ras. An auxiliary electrode is electrically connected to the counter electrode and overlaps portions between the pixel electrodes. The wafer holding table and polishing platen are then rotated to perform polishing with chemical liquid dropped on the polishing cloth. 5 mm to 5 mm and a standard deviation \u03c3 for that crystal grain diameter of no more than 2 mm. Wide viewing angle is obtained by four domains where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases. Optionally, a clearance structure of the frame receives a shaft of the actuator motor, and a passage from the control circuit enclosure to the clearance structure provides access for electrical power and sensor information between the control circuit to the actuator motor.
