Abstract

PURPOSE:To obtain a sticky and fixable polarizing plate for a liq. crystal display element capable of performing a whitened fixed display without applying a voltage by stretching polyvinyl alcohol with iodine adsorbed thereon and irradiating the resulting polarizer with ultraviolet rays to sublime and remove iodine in the form of a desired pattern. CONSTITUTION:A polarizer 12 is obtd. by stretching polyvinyl alcohol and has iodine adsorbed on the whole surface. A stainless steel mask 5 having a formed desired pattern is mounted on the polarizer 12, and the polarizer 12 is irradiated with ultraviolet rays from carbon arc 6 through the mask 5 for 20min. At the irradiated part iodine is sublimed and removed, and the part is deprived of the polarizing power. Supports 3 made of cellulose triacetate are then adhered to both sides of the patterned polarizer 12, and by coating one side of the resulting polarizing plate 11 with a pressure sensitive adhesive 4, a sticky polarizing plate enabling a whitened fixed display can be formed.

Ultraviolet light was applied to the polarized light 112 through the f-star 5 for 20 minutes. As a result, the decimated 11 minutes are removed by sublimation of four IIAs, which lose their unitary ability.Then, this 15-pattern shape is used, and nine polarizers, 120 mK1 and 3A, are added to the triacetate cell to accommodate - Glue the supporting weight consisting of nu.

At 1 tC for 1 minute, the part is wrapped in a no-electric field state, but the part with one bulk removed always passes through the part regardless of the electric field, and a fixed display of self-extraction can be formed.

As explained above, according to the method of manufacturing the scratched material according to the present invention, a desired pattern is obtained by adsorbing and stretching the element KM'), and then irradiating it with nine photons KM'. By sublimating and removing the offending element, the polarizing ability of that part can be lost. For this reason, a! It has the advantage that it can be used in a crystal display element to display a white 1011 constant without applying a voltage.
