Embodiment 1

[0133]

[0134] After biaxially stretching polycarbonate (PC-2151, thickness 250 μm) manufactured by TEIJIN LIMITED. at 150°C to 30% in the longitudinal direction and 30% in the transverse direction, the method described in Example 1 of US2013 / 0341074 A transparent conductive layer was fabricated using Ag nanowires, and a laminate was produced in which a plastic substrate containing polycarbonate and a transparent conductive layer containing Ag nanowires were laminated.

[0135]

[0136] The laminate produced above was cut into 6 cm in length and 10 cm in width, and a polyamic acid alignment layer coating solution (JALS684 manufactured by JSR Corporation) was applied as a liquid crystal aligning agent using bar coater #1.6. After that, it was dried at a film surface temperature of 80° C. for 3 minutes, thereby producing an alignment layer 101 . At this time, the film thickness of the alignment layer was 60 nm.

[0137] Two sets of laminates were prepared in which the plas...

Abstract

The present invention addresses the problem of providing: a plastic cell having a sealing portion that maintains the ability to remain sealed even when a plastic substrate deforms into any shape having irregularities and curved surfaces; and a method for manufacturing the plastic cell. The plastic cell according to the present invention has a first plastic substrate, a first transparent conductivelayer, a fluid layer, a second transparent conductive layer, and a second plastic substrate in this order. Additionally, the plastic cell has a sealing portion in which a portion of the first plasticsubstrate or the second plastic substrate is deformed so as to seal the fluid layer. The sealing portion includes a corrugated region that satisfies the following expression (1): P <= 40A (1) Where Prepresents the corrugation pitch, and A represents the corrugation amplitude.

Description

technical field [0001] The present invention relates to a plastic unit using a plastic substrate and a manufacturing method thereof. Background technique [0002] In recent years, liquid crystal display devices have evolved into various forms, and lightweight and bendable flexible displays have attracted attention. In liquid crystal cells used in such flexible displays, conventionally used glass substrates are difficult to meet the requirements of light weight and bendability, so various plastic substrates have been studied instead of glass substrates. [0003] In addition, the use of liquid crystal cells has also expanded to light-adjusting devices used in applications such as packaging, decoration, decoration, building materials, and vehicles. Lightweight and bendable flexibility is also desired in these light-adjusting devices. The free shape of the two-dimensional plane is not used, and the substrates in these applications are also required to use plastic substrates ins...
