Abstract

This invention provides a light-emitting display device that comprises a light-emitting part and a package part. The package part covers a top opening of the light-emitting part, and includes a brightening-antireflective structure. The brightening-antireflective structure has a linear polarizing layer, a quarter-wave plate and an antireflective layer. The linear polarizing layer is disposed apart from the light-emitting part. The linear polarizing layer permits a linear-polarized light with a first linear polarization direction passing through, and blocks a linear-polarized light with a second linear polarization direction. The quarter-wave plate is disposed adjacent to the light-emitting part. The quarter-wave plate coverts a linear-polarized light with the first linear polarization direction or a circularly-polarized light with a first circular polarization direction into one another, and converts a linear-polarized light with the second linear polarization direction or a circularly-polarized light with a second circular polarization direction into one another. The antireflection layer is disposed between the linear polarizing layer and the quarter-wave plate. The antireflection layer permits a linear-polarized light with the first linear polarization direction passing through, and reflects a linear-polarized light with the second linear polarization direction.

Description

technical field [0001] The invention relates to a light-emitting display device, in particular to a light-emitting display device provided with a reflective polarizing layer. Background technique [0002] The current organic light-emitting touch display device generally includes an organic light-emitting component, a packaging substrate, a touch sensing structure, an anti-reflection structure and a cover plate. The organic light emitting component provides a light source of the display device, and includes a plurality of organic light emitting diodes. The packaging substrate seals the organic light-emitting components inside, so as to prevent the organic light-emitting diodes from being damaged by components such as moisture and oxygen in the external environment. The touch sensing structure includes a structure of a substrate and a touch electrode to provide a touch sensing function. The anti-reflective structure includes multiple optical layers that slow the reflection o...
