SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF, DISPLAY APPARATUS AND ELECTRONIC APPARATUS

摘要

A semiconductor device including: a first electric conductor of a lower layer side and a second electric conductor of an upper layer side; a thick film insulating layer provided between the first electric conductor and the second electric conductor; and a contact portion formed so as to imitate an inner surface shape of a through hole with respect to the insulating layer and electrically connecting the first electric conductor and the second electric conductor, in which a tapered angle of the through hole is an acute angle.
