Liquid crystal screen display
View Patent ↗A liquid crystal screen display is disclosed which is capable of restraining occurrence of display unevenness. In the display of the invention, a conductive member to which a negative voltage is applied is placed between a substrate and an alignment layer so as to be in partial contact with the alignment layer. Uneven ion distribution attributable to ion generation within broken or pin hole parts of an overcoat film is restrained, for instance, by exposing gate signal lines etc. to the alignment layer so that ions are intentionally generated in the regions of the liquid crystal layer corresponding to the exposed regions.
1. A liquid crystal screen display comprising:
a first insulating substrate;
a second insulating substrate facing the first insulating substrate;
a liquid crystal layer formed between the first and second insulating substrates;
alignment layers formed between the first insulating substrate and the liquid crystal layer and between the second insulating substrate and the liquid crystal layer, respectively, for aligning the liquid crystal layer; and
a first conductive member which is formed between at least either one of the first and second insulating substrates and its corresponding alignment layer, being in partial contact with the alignment layer and to which a negative voltage is applied, wherein
an electrolyte is added to the liquid crystal layer.
2. The liquid crystal screen display according to claim 1 , wherein the electrolyte is a compound given by the chemical formula (t-Bu)hd 4 NX, where X of the chemical formula is halogen.
3. The liquid crystal screen display according to claim 1 , wherein the electrolyte is a compound given by the chemical formula (t-Bu)hd 4 NX, where X of the chemical formula is COOR (in which R is hydrogen, a hydro carbon group or alkali metal).
