Patent ID: 7233021

Claim:
An active matrix substrate, comprising: an insulating substrate having formed thereon a plurality of electrode lines arranged in matrix form, an active element provided at each intersection between said electrode lines, an interlayer insulating layer formed over said electrode lines and said active elements, and a plurality of pixel electrodes formed on said interlayer insulating layer, wherein said interlayer insulating layer is formed so as to cover a pixel array region in which said electrode lines are arranged in matrix form and at least partially cover a marginal region surrounding said pixel array region; and an uneven section is provided in/on at least a part of an upper surface of said interlayer insulating layer, wherein said uneven section is formed at least at said marginal region, said uneven section comprising at least a concave and/or convex part, and wherein the concave and/or convex part is provided independently of stepped parts of layers below the interlayer insulating layer, and wherein a surface of said uneven section is covered with an inorganic material.
