Abstract

A display includes a first substrate, a second substrate, a liquid crystal layer, a backlight source, a driving integrated circuit and a conductive portion. The liquid crystal layer is disposed between the first substrate and the second substrate. The backlight source is disposed at a first side of the second substrate. The driving integrated circuit is disposed at a second side, opposite to the first side, of the second substrate. The conductive portion is electrically coupled to the driving integrated circuit and passes through the second substrate to be electrically coupled to the backlight source. Furthermore, a display manufacturing method thereof is also disclosed here.

Claims4

Dependent claims

A manufacturing method of a display device, comprising:

providing a first substrate, a second substrate, and a liquid crystal layer disposed therebetween;
forming a conductive portion which is disposed on and passes through the second substrate;
electrically coupling a flexible circuit board to the conductive portion at a side of the second substrate facing away the first substrate;
cutting the first substrate from an edge of the first substrate after the flexible circuit board is electrically coupled to the conductive portion;
and
disposing an integrated driving circuit at a side of the second substrate facing the first substrate and electrically coupling the integrated driving circuit to the flexible circuit board through the conductive portion after the edge of the first substrate is cut.
