A display device and a method for manufacturing the display device are provided. The display device includes an organic layer on an auxiliary wiring is removed with high precision by one operation and, thereby, the yield and the productivity are improved. A lower electrode is formed by patterning in each pixel on a substrate. An auxiliary wiring including a light absorption layer is formed between individual pixels. An organic layer is formed on the substrate while covering the lower electrodes. Laser irradiation is conducted from the organic layer side, the laser light is converted to heat in the light absorption layer exposed at a portion under the organic layer, and the organic layer portion above the light absorption layer is removed selectively. An upper electrode is formed on the organic layer and is connected to the light absorption layer portion of the auxiliary wiring.

摘要:
A liquid crystal display element is produced by forming an electrical insulating metal oxide film on a transparent glass substrate, forming a transparent conductive film thereon by coating a coating solution prepared by diluting a solute comprising indium, tin, a .beta.-diketone and nitric acid with an organic solvent, followed by calcination, etching the transparent conductive film to give electrodes having desired patterns, placing the two resulting glass substrates in parallel so that individual electrodes at the inner side stand opposite to each other, and enclosing a liquid crystal material in the space formed between the two glass substrates. The liquid crystal display element thus produced has transparent electrodes which have low sheet resistance, enhanced mechanical strength and strong adhesive strength to the glass substrate.
