Abstract
An organic thin film transistor having a semiconductor active layer containing a compound represented by the formula (1) has a high carrier mobility and a small change in the threshold voltage after repeated operation. R1 to R10 represent H or a substituent, provided that any two adjacent members among R1 to R4 and R6 to R9 are bonded to each other to form a substituted or unsubstituted benzene ring.
