    • PURPOSE: A substrate for a display device is provided to reduce flatness and moisture permeability and to improve flex resistance, flexibility, and durability. CONSTITUTION: A substrate for a display device comprises a matrix(2), a reinforcing agent(1) impregnated in a matrix, a coating layer formed on at least one side of the matrix, and a barrier layer(4) formed on one side of the coating layer. If the elastic modulus of the matrix is E2 at 25°C and the elastic modulus of the coating layer is E3 at 25°C, E3/E2 is 5 x 10^4 or less. The coating layer has a gradient elastic modulus structure. The elastic modulus of the matrix at 25°C is 0.1GPa or less. The elastic modulus of the coating layer is 0.1GP-10GPa. The elastic modulus of the barrier layer is 10GPa or more. The coating layer comprises one or more selected from an acrylic-based resin, epoxy-based resin, silicon-based resin, urethane-based resin, and unsaturated polyester-based resin.
    • 目的:提供一种用于显示装置的基板,以减少平坦度和透湿性,并提高抗挠曲性,柔韧性和耐久性。 构成:用于显示装置的基板包括基体(2),浸渍在基体中的增强剂(1),形成在基体的至少一侧上的涂层和形成在一侧的阻挡层(4) 的涂层。 如果基体的弹性模量在25℃为E2,涂层的弹性模量在25℃为E3,则E3 / E2为5×10 ^ 4以下。 涂层具有梯度弹性模量结构。 25℃下的基体弹性模量为0.1GPa以下。 涂层的弹性模量为0.1GP-10GPa。 阻挡层的弹性模量为10GPa以上。 涂层包含选自丙烯酸系树脂,环氧类树脂,硅系树脂,氨基甲酸酯系树脂,不饱和聚酯系树脂等中的一种以上。
