Abstract:
A liquid crystal display device, comprising:a first electrode including an Al or Al alloy layer; a pixel electrode provided above the first electrode, and at least two interlayer insulator layers interposed between the first electrode and the pixel electrode so as to cover the first electrode, wherein the two interlayer insulator layers include a first interlayer insulator layer comprising an inorganic insulator film and a second interlayer insulator layer comprising an organic insulator film, the first and second interlayer insulator layers being provided in this sequence with no other layer at any point therebetween when viewed from the first electrode, so that the second interlayer insulator layer is formed directly on the first interlayer insulator layer, wherein the first electrode serves as a source electrode, a gate electrode including an Al or Al alloy layer provided below the source electrode, the source electrode including at least a first source electrode layer comprising at least one of TiN, Ta, Ti, Cr, Mo, and MoN, and a second source electrode layer comprising said Al or Al alloy layer of said first electrode, the first and second source electrode layers being provided in sequence, and wherein the first source electrode layer and the pixel electrode are provided so as to cover a terminal section of the gate electrode that serves as a connecting terminal outside of a pixel area of the display device.
