Abstract

An etchant for selective etching is used to simplify the production process of a semi-transparent semi-reflective electrode substrate, and temporal loss is not produced by avoiding troublesome repeated works, thereby efficiently providing a semi-transparent semi-reflective electrode substrate. A method for manufacturing a semi-transparent semi-reflective electrode substrate where a metal oxide layer (12) made of at least indium oxide and an inorganic compound layer (14) at least made of Al or Ag are formed in order of mention. The method comprises a step of etching the inorganic compound layer (14) with an etchant lambda composed of phosphoric acid, nitric acid, and acetic acid and a step of etching the metal oxide layer (12) with an etchant sigma containing oxalic acid.

Description

technical field

[0001] The invention relates to a method for manufacturing a transflective and semireflective liquid crystal electrode substrate. It also relates to an etchant used in the manufacture of a transflective electrode substrate.

[0002] Also, the present invention relates to a reflective electrode substrate in a reflective liquid crystal or a light-emitting element, a method for producing the same, and an etching solution used in the method for producing the same. Background technique

[0003] One of the existing technologies (semi-transmissive and semi-reflective liquid crystal)

[0004] Hitherto, research and development of transflective liquid crystals have been vigorously conducted for the reasons described below.

[0005] (1) Since it is semi-transmissive and semi-reflective, a bright display can be obtained regardless of whether it is outdoors or indoors.

[0006] (2) When used in a bright place, it can be used as a reflection type, so power consumption ...
