Abstract
In a display device having, at least, picture elements which are arrayed on a transparent insulating substrate, and transistor portions which are formed of a semiconductor layer formed on the transparent insulating substrate; a display device characterized in that, at least, interconnection parts of the transistor portions extend above the semiconductor layer formed on the transparent insulating substrate. The disconnection of the interconnection parts can be avoided.
Claims7
An active matrix display device comprising:
- picture elements which are arrayed on a transparent insulating substrate;
- a semiconductor layer formed on said transparent insulating substrate;
- a transistor matrix which is formed using said semiconductor layer;
- and
- bus conductors coupled to said transistor matrix,
- wherein said semiconductor layer is formed in the shape of a mesh, and said bus conductors extend only inside an area where said mesh-shaped semiconductor layer exists so as not to extend over edges of said mesh-shaped semiconductor layer.
