Method for manufacturing display device
First Claim
1. A method for manufacturing a display device comprising:
- forming a light-absorbing layer;
forming an insulating layer over the light-absorbing layer;
selectively emitting a laser light to the light-absorbing layer and the insulating layer to remove an irradiated region of the light-absorbing layer and an irradiated region of the insulating layer, so that an opening is formed in the light-absorbing layer and the insulating layer; and
forming a conductive film in the opening so as to be in contact with the light-absorbing layer, andwherein the light-absorbing layer contains a conductive material.

Abstract
An object is to provide a display device that can be manufactured with increased use efficiency of a material by a simplified manufacturing process and a manufacturing technique thereof. A light-absorbing layer is formed, an insulating layer is formed over the light-absorbing layer, the light-absorbing layer and the insulating layer are selectively irradiated with laser light, so that an irradiated region of the light-absorbing layer and an irradiated region of the insulating layer are removed, and accordingly an opening is formed in the light-absorbing layer and the insulating layer, and a conductive film is formed in the opening so as to be in contact with the light-absorbing film. The conductive film is formed in the opening so as to be in contact with the exposed light-absorbing layer, so that the light-absorbing layer and the conductive film are electrically connected to each other with the insulating layer interposed therebetween.
