The invention discloses a large visual angle integrated black display device, which comprises a cover plate and a display module, and is characterized in that the cover plate comprises an ink layer with a hollow structure, a color ink layer printed on the surface of the ink layer with the hollow structure, and a shielding ink layer printed on the surface of the color ink layer. The color ink is printed on the ink layer with the hollow-out structure, so that when light is reflected from the composite coating, the light can react with the hollow-out structure, a value a and a value b are greatly shifted, and the change of the value a and the value b is realized. As the microstructure of the coating is similar to the microstructure of the display screen module, good integrity can be achieved when the display screen module is observed from different angles. 本发明公开了一种大视角一体黑显示装置，包括盖板和显示模组，其中，盖板包含具有镂空结构的油墨层，印刷在具有镂空结构的油墨层表面的彩色油墨层以及印刷在彩色油墨层表面的遮蔽油墨层。通过在具有镂空结构的油墨层上印刷彩色油墨，从而使光从复合涂层上反射时，能与镂空结构发生作用，使a、b值发生较大偏移，从耐实现a、b值发生变动。
