Abstract
A light-emitting display device is provided. The light-emitting display device includes a first substrate, a first electrode layer on the first substrate, a bank layer that has openings exposing part of the first electrode layer, an emissive layer on the first electrode layer, bank grooves formed by recessing the bank layer, a second electrode layer on the emissive layer, and a low-reflectivity layer that lies on the second electrode layer and is positioned to correspond to the bank grooves.
Claims8
A light-emitting display device comprising:
- a first substrate;
- a first electrode layer on the first substrate;
- a bank layer having an opening exposing part of the first electrode layer;
- an emissive layer disposed on the first electrode layer;
- a bank groove formed by recessing the bank layer;
- a second electrode layer disposed on the emissive layer;
- and
- a polarization layer disposed on the second electrode layer and is positioned to correspond to at least part of the bank layer,
- wherein the emissive layer has a first portion disposed inside the bank groove and a second portion disposed outside the bank groove and the first and second portions are disconnected from each other,
- wherein the polarization layer includes first and second polarization layers that have different polarization properties from each other,
- wherein the first polarization layer and the second polarization layer are located in different positions, and
- wherein at least one of the first polarization layer and the second polarization layer is directly located on a same layer as the first electrode layer is located, and another one of the first polarization layer and the second polarization layer is indirectly located on the second electrode layer.
