  A waveguide device comprising at least a waveguiding layer, a cladding layer and, optionally, an adhesion-enhancing layer is disclosed. By using specific fluorinated polyimides as materials for each of the layers of the waveguide device, the process for producing the waveguide device is simplified, the production cost is reduced, and the flexibility is imparted to the waveguide device, which are not achieved in a quartz-type waveguide. Also, a single mode, a low loss at 1.3 micron band and a high moisture-resistance which are not achieved by conventional plastic-type waveguide are possible.

  The present invention relates to a modified polyimide including a terminal group represented by Formula 1: wherein D is a heat curable or photocurable functional group, R is a divalent or higher polyvalent organic group, and n is an integer of 1 or greater. The modified polyimide undergoes less reduction in transmittance and is protected from discoloration when cured. Due to these advantages, the modified polyimide can provide a highly transparent colorless polyimide film. Particularly, the modified polyimide is suitable for use in display substrates, interlayer insulating films of semiconductor devices, passivation films, buffer coat films, insulating films for multilayer printed circuit boards, insulating films of OLEDs, and protective films of thin film transistors of liquid crystal display devices. The present invention also relates to a curable composition including the modified polyimide.

  本发明涉及一种改性聚酰亚胺，包括由式 1 表示的端基： 其中 D 是热固化或光固化官能团，R 是二价或更高价的多价有机基团，n 是 1 或更大的整数。改性聚酰亚胺的透光率降低较少，固化后不会变色。由于这些优点，改性聚酰亚胺可以提供高透明度的无色聚酰亚胺薄膜。改性聚酰亚胺尤其适用于显示器基板、半导体设备的层间绝缘膜、钝化膜、缓冲涂层膜、多层印刷电路板的绝缘膜、有机发光二极管的绝缘膜以及液晶显示设备薄膜晶体管的保护膜。本发明还涉及一种包括改性聚酰亚胺的固化组合物。
