Abstract
The invention provides an organic luminous display device. A shading layer which surrounds a display region is arranged in a non-display region and is provided with an emergent opening; the area of the opening is equal to that of the display region; The shading layer is arranged at the outer side of a base plate; light rays emitted from the display region are ejected from the emergent opening; due to the restriction of the shading layer, the light rays emitted from the display region can not be subjected to a refraction phenomenon, so that the occurrence of a ghost phenomenon is effectively prevented; the shading layer is also can be arranged between the base plate and the organic light-emitting diode or between layers in the organic light-emitting diode; when the light rays emitted from the display region are refracted by virtue of the base plate, refractive light rays are absorbed by the shading layer, so that the ghost phenomenon can not be generated, therefore the definition of the display region is improved, and the display quality is improved.
