1. An image display device formed on an insulation substrate, comprising:
an image display panel including a plurality of pixel display circuits arranged in a plurality of rows and a plurality of
columns, a plurality of scan lines provided in correspondence with said plurality of rows, respectively, and a plurality of
data lines provided in correspondence with said plurality of columns, respectively;
a plurality of transistors having first electrodes connected to said plurality of data lines, respectively, and made nonconductive
when said image display panel is in normal operation;
a first inspection terminal connected to second electrodes of the odd-numbered transistors among said plurality of transistors;
a second inspection terminal connected to second electrodes of the even-numbered transistors among said plurality of transistors;
and
a first control terminal connected to gates of said plurality of transistors, and receiving a control signal for controlling
said plurality of transistors at inspection of said image display panel.
