摘要

本发明提供一种显示或照明装置，其使用薄膜电晶体作为驱动用元件，所述薄膜电晶体含有包含光劣化大的物质的半导体层，并且伴随着该些装置的使用的所述物质的光劣化得到抑制。本发明的显示或照明装置具备：TFT基板；第1电极，设置于TFT基板上且与所述TFT连接；绝缘膜，以使第1电极局部地露出的方式形成于第1电极上，且全光线透射率于波长300nm~400nm下在0%~15%的范围内；以及第2电极，与第1电极相对向而设置；并且所述绝缘膜为由感放射线性材料所形成的绝缘膜，所述感放射线性材料含有(A)聚合物、(B)感光剂及(C)酚醛清漆树脂等树脂，且相对于聚合物(A)100质量份，所述感放射线性材料中的树脂(C)的含量为2质量份~200质量份。; a first electrode, disposed on the TFT substrate and connected to a TFT; an insulating film, formed on the first electrode to partially expose the first electrode, a total light transmittance of which is in a range of 0%-15% in a wavelength of 300 nm-400 nm; and a second electrode, disposed opposite to the first electrode. The insulating film is formed with a radiation-sensitive material. The radiation-sensitive material includes (A) a polymer, (B) a photosensitizer and (C) a resin such as novolak resin. The content of the resin (C) in the radiation-sensitive material is 2-200 parts by weight with respect to 100 parts by weight of the polymer (A).
