The present invention relates to pyrido3,2-hquinazolines andor 5,6-dihydro derivatives thereof, methods for their production and doped organic semiconductor material which use such quinazolines. The flexible substrate may include a first film having a glass cloth located within a first heat-resistant resin, and a second film laminated on at least one side of the first film. The method also includes storing a first threshold in the memory unit, determining a current input speed of the drive unit with the speed sensor, and comparing the current input speed to the first threshold. The transparent insulation layer is disposed on the touch electrode layer and formed with at least one through hole. Furthermore, the second high refractive index material layer is selectively etched by utilizing a dry-etching tool with high selectivity to the etch mask layer, and a second low refractive index material layer is deposited as a top cladding layer to encapsulate the second high refractive index material layer on top of lower cladding layers. The pair of cylinders pivot the inner bearings supported by one of the frames and the outer bearing.
