The present invention stably fixes a resin molded body without exposing undulations on the surface of a display panel when the resin molded body, such as a locking portion for fixing to a housing, is integrally provided on the back surface side of a thin glass display panel. A display panel (1) is formed by integrally fixing a resin molded body (3), which is a locking portion, to the rear surface of a glass substrate (2). A resin containing a thermoplastic elastomer and having a tensile modulus of elasticity of 100 MPa or less is used as a material for use of the resin molded body (3). The tensile modulus of elasticity of the resin molded body (3) is small, and the compressive force of the resin during molding is suppressed to be small, thereby suppressing the occurrence of undulations on the glass surface.
本发明将用于固定于壳体的卡止部位等树脂成型体一体地设置于薄壁的玻璃制显示面板的背面侧时,不在显示面板的表面露出起伏地使树脂成型体稳定地固定。显示面板1是将作为卡止部位的树脂成型体3一体地固定于玻璃基材2的背面而形成的。使用包含热塑性弹性体且拉伸弹性模量为100MPa以下的树脂作为树脂成型体3的使用材料。通过树脂成型体3的拉伸弹性模量较小,将成型时的树脂的压缩力抑制得较小,抑制玻璃表面的起伏的产生。
