Method for forming color filter, method for forming light emitting element layer, method for manufacturing color display device comprising them, or color display device

摘要

After a gate line (11), a TFT (1), and a data line (30) are formed, a riblike protective insulation layer (32) which coats the data line is formed on a substrate (10) serving as the element substrate of an active matrix type color liquid crystal display device or an organic EL display device. A color filter layer (42) on a transfer film (40) is press-bonded on this substrate (10) with a roller (46) moving in the extensional direction (columnar direction) of the protecting insulation layer (32). The advancement of the transfer of a color filter in the columnar direction makes it possible to bring the substrate and the color filter in contact without gaps while expelling the gas out of a pixel space in the advancement direction. During the step of forming a color filter, the protecting insulation layer (32) protects the data line (30) from the treatment liquid etc. An organic light emitting element layer is arranged in the pixel space to form an organic EL display device.
