Abstract:
A method for forming walls (8) between substrates (11, 12) in a liquid crystal cell (10) includes the step of forming a cell with a liquid crystal-monomer mixture (50). The cell (10) is then exposed to ultraviolet light (70) causing the monomer to be selectively polymerized to form walls (8) between substrates (11, 12) of the cell. The monomer is selectively polymerized by applying an electric field across the cell through a patterned conductive coating (31, 32) on each substrate (11, 12) to separate the dispersed monomer to the low field, interpixel regions (72). The cell (10) is then exposed to ultraviolet light (70) to polymerize the separated monomer to form the walls (8) in the low field regions (72).
Abstract:
The invention relates to a process for chemically etching a layer (2) having electrical conduction properties, on a transparent substrate (1) of the glass type. It includes at least one step of depositing a mask (3) comprising at least one hot-melt ink on the layer to be etched.
