Array substrate for an image display device

An image display device comprising:

• a substrate;
• a lower layer interconnect line formed over said substrate;
• a first insulation layer formed over said lower layer interconnect line;
• an upper layer interconnect line formed in a predetermined pattern configuration on said first insulation layer, said upper layer interconnect line and said first insulation layer in combination forming a step, said upper layer interconnect line intersecting said lower layer interconnect line through said first insulation layer;
• a second insulation layer formed on said upper layer interconnect line and including a surface of an uneven configuration dependent on said step;
• a reflective electrode formed on said second insulation layer and including a surface of an uneven configuration dependent on said uneven configuration of said surface of said second insulation layer;
• and
• a third insulation layer in contact with said first insulation layer and formed under said first insulation layer, said third insulation layer having a high etch selectivity to said first insulation layer,
• wherein said first insulation layer is of the same configuration as said pattern configuration.
