RED SEMICONDUCTOR LIGHT-EMITTING DEVICE FOR DISPLAY PIXELS, AND DISPLAY APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/076160
Kind Code:
A1
Abstract:
An embodiment relates to a red semiconductor light-emitting device for display pixels, and a display apparatus comprising same. The red semiconductor light-emitting device for display pixels, according to the embodiment, may comprise: a first semiconductor light-emitting structure including a first conductive first semiconductor layer, a first active layer on the first conductive first semiconductor layer, and a second conductive second semiconductor layer on the first active layer; a tunnel junction structure on the first semiconductor light-emitting structure; and a second semiconductor light-emitting structure including a first conductive third semiconductor layer arranged on the tunnel junction structure, a second active layer on the first conductive third semiconductor layer, and a second conductive fourth semiconductor layer on the second active layer. The tunnel junction structure can comprise: a second conductive first tunnel junction layer arranged on the second conductive second semiconductor layer; and a first conductive second tunnel junction layer arranged on the second conductive first tunnel junction layer.
