Organic light emitting display device with at least one light blocking layer

An organic light emitting display device, comprising:

• a substrate;
• a plurality of first sub-pixels including a first electrode, a light emitting layer on the first electrode, a second electrode on the light emitting layer, and a driving transistor on the substrate, the first electrode connected to the driving transistor, the plurality of first sub-pixels emitting light of a first color;
• a plurality of second sub-pixels on the substrate, the plurality of second sub-pixels emitting light of a second color;
• a first bank layer between a first sub-pixel of the plurality of first sub-pixels and a second sub-pixel of the plurality of second sub-pixels, the first bank layer extending in a first direction;
• a second bank layer between adjacent first sub-pixels of the plurality of first sub-pixels, the second bank layer extending in a second direction;
• a first light blocking layer overlapping the first bank layer and provided under the first bank layer;
• a second light blocking layer overlapping the second bank layer and provided under the second bank layer;
• and
• a sensor module under the substrate, the sensor module detecting light,
• wherein the first light blocking layer is between the driving transistor and the second electrode in a cross-sectional view of the organic light emitting display device,
• wherein the first light blocking layer overlaps in part with the driving transistor in a plan view of the organic light emitting display device,
• wherein the sensor module overlaps the first light blocking layer and the second light blocking layer, and
• wherein the first bank layer is provided on the first electrode, a partial region of an upper surface of the first electrode exposed to become a light emitting region without being covered by the first bank layer.
