Abstract
An electronic device of the present invention includes a shift register SR provided integrally with a substrate, a first line 11 connected with a connection terminal 101 electrically connectable with an outside device provided independently of the shift registers SR, second lines 12a through 12c via which output waveforms of the shift register SR are extracted, and switching sections 13a through 13c by which the first line 11 and the second lines 12a through 12c are switched between an electrically connected condition and an electrically disconnected condition. With this, even in a case where the electronic device of the present invention is a liquid crystal display device having a driver monolithic structure, output waveforms of a drive circuit (electronic circuit) can be inspected.
