Abstract:
1. A manufacturing method for a liquid crystal display device comprising the steps of: forming on a first substrate gate bus lines supplied with scanning signals, data bus lines supplied with display signals, thin-film transistors having gate electrodes connected to the gate bus lines and drain electrodes connected to the data bus lines; forming a photoresist film on upper part of the gate bus lines, the data bus lines, and the thin-film transistors; dividing the photoresist film for each picture element and exposing and developing photoresist to form opening parts at positions corresponding to source electrodes of the thin-film transistors; changing inner stresses in a thickness direction of the photoresist film; subjecting the photoresist film to heat treatment to form wrinkle-form surface ruggedness; forming on the photoresist film reflection electrodes electrically connected to the source electrodes of the thin-film transistors via the opening parts; and arranging opposingly the first substrate and a second substrate provided with an electrode made of a transparent conductive film, and enclosing liquid crystal therebetween.
