Abstract
A liquid-crystal display panel 20 comprises a first substrate 30 having an IC chip 60 mounted on the margin thereof and a second substrate 50 opposed to the first substrate 30 except the margin 31 on which the IC chip 60 is mounted. The first substrate 30 has two rows of pads 33 and 34, which are used to attach the IC chip 60, arranged nearly parallel to a side of the second substrate 50 adjoining the margin 31 on the margin 31 on which the IC chip 60 is mounted. A wiring pattern of lines passing through the pads on the row of pads 33 near the adjoining side of the second substrate 50 out of the rows of pads 33 and 34 includes a straight wiring-pattern part 38 extended straight to the inside of an IC chip mounting region 40 or a region in which the IC chip 60 is mounted. As such, a liquid-crystal display panel is provided which is capable of being tested for lighting prior to mounting of an IC chip even though a wiring pattern surrounding the IC chip on a liquid-crystal substrate is very short.
