摘要:
A first member and a second member constituting flow passage member are joined at a first joining region that surrounds the periphery of a liquid flow passage and a second joining region that is further to the outside than the first joining region, and in a state where the second joining region has a gas barrier property higher than that of the first joining region, the second joining region seals a gap between the first member and the second member, wherein the liquid ejecting head includes a communication hole that communicates a space between the first member and the second member with the outside, which is surrounded by the first joining region and the second joining region.

摘要:
A manufacturing method for a horizontal electric field type liquid crystal display device of fringe field switching (FFS) or the like mode whereby pixel electrodes and a common electrode are disposed opposing each other on a planarization layer with an insulator interposed, includes a step whereby a planarization layer 18 is formed that has openings formed therein at the positions where contact holes 21a are to be formed in the surface of a passivation layer 17, and the portions of such planarization layer at the periphery of the display area are removed, followed by a step whereby the exposed portions of the passivation layer 17 are removed using a fluorine etching gas. By employing such method, the size of the contact hole 21a mouths can be rendered smaller, and also the number of manufacturing processes can be reduced, compared to the related art.
