Title:
DISPLAY DEVICE, AND ELECTRONIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2022/085749
Kind Code:
A1
Abstract:
Provided is a display device which is capable of suppressing color mixing of light, and which has an excellent light extraction efficiency. This display device is provided with: a plurality of sub-pixels which form pixel units and which correspond at least to red, green, and blue color types; a plurality of light emitting elements which are formed corresponding to each sub-pixel, and which have a structure in which a first electrode and a second electrode are stacked sandwiching an organic compound layer; and at least one lens formed to correspond to each sub-pixel. Each light emitting element is provided with an insulating layer which covers a peripheral edge portion of the first electrode, and in which an opening portion is formed on the first electrode to correspond to each sub-pixel, wherein formula 1 and formula 2 are satisfied. (Formula 1): ΣLR/WR<ΣLB/WB (Formula 2): ΣLG/WG<ΣLB/WB (Where, in formula 1 and formula 2, WR, WG, and WB are respectively the width in the horizontal direction of the opening portions corresponding to the red, green, and blue sub-pixels. ΣLR represents the width in the horizontal direction of the bottom surface of the lens formed to correspond to the red sub-pixel if a first horizontal arrangement number is 1, and represents the sum of the widths in the horizontal direction of the bottom surfaces of each lens formed side by side in the horizontal direction to correspond to the red sub-pixels if the first horizontal arrangement number is 2 or more. ΣLG represents the width in the horizontal direction of the bottom surface of the lens formed to correspond to the green sub-pixel if a second horizontal arrangement number is 1, and represents the sum of the widths in the horizontal direction of the bottom surfaces of each lens formed side by side in the horizontal direction to correspond to the green sub-pixels if the second horizontal arrangement number is 2 or more. ΣLB represents the width in the horizontal direction of the bottom surface of the lens formed to correspond to the blue sub-pixel if a third horizontal arrangement number is 1, and represents the sum of the widths in the horizontal direction of the bottom surfaces of each lens formed side by side in the horizontal direction to correspond to the blue sub-pixels if the third horizontal arrangement number is 2 or more.)
