FINGERPRINT SENSING UNIT AND DISPLAY DEVICE INCLUDING THE SAME

A fingerprint sensing unit includes a substrate; a buffer layer disposed on the substrate; a thin film transistor disposed on the buffer layer; an insulating layer disposed on the buffer layer and that has an opening that exposes at least a portion of the buffer layer; and a sensing electrode disposed on the portion of the buffer layer that is exposed by the opening, where the sensing electrode isconnected to the thin film transistor. A display device that includes the fingerprint sensing unit can reduce internal reflection of external light. 本公开提供一种指纹感测单元和一种包括该指纹感测单元的显示装置。所述指纹感测单元包括：基底；缓冲层，设置在基底上；薄膜晶体管，设置在缓冲层上；绝缘层，设置在缓冲层上并且具有暴露缓冲层的至少一部分的开口；以及感测电极，设置在缓冲层的被开口暴露的所述至少一部分上，其中，感测电极连接到薄膜晶体管。包括指纹感测单元的显示装置可以减少外部光的内部反射。
