A wearable device includes a physiological information detecting device, which includes a flexible display panel, a flexible circuit board, a light sensor and a physiological information calculating module. The flexible display panel includes a first light permeable surface and a second light permeable surface opposite to each other, and a first OLED unit and a second OLED unit sandwiched between the first and second light permeable surfaces. The first OLED unit and the second OLED unit respectively emit lights through the first and second light permeable surfaces. The light sensor is disposed on the flexible circuit board, and it includes a sensing surface, in which the sensing surface and the first light permeable surface faces toward the same orientation, so that the sensing surface detects the light reflected by a living being when the living being is emitted by the first OLED unit. The physiological information calculating module obtains the physiological information based on the reflected light.一種穿戴式裝置包含生理資訊感測裝置,其包含可撓性顯示面板、可撓性電路板、光感測器以及生理資訊運算模組。可撓性顯示面板包含相對的第一透光面與第二透光面、及位於兩者間的第一有機發光二極體單元及第二有機發光二極體單元。第一有機發光二極體單元與第二有機發光二極體單元分別通過第一透光面與第二透光面出光。光感測器係設置於可撓性電路板上,其包含與第一透光面朝向相同方位的感測面,以感測第一有機發光二極體單元照射生物後所反射之反射光線。生理資訊運算模組係根據反射光線得到生物之生理資訊。10‧‧‧穿戴式裝置100‧‧‧弧形骨架110‧‧‧第一彎曲體111‧‧‧第一末端部120‧‧‧第二彎曲體121‧‧‧第二末端部200‧‧‧可撓性顯示面板210‧‧‧第一有機發光二極體單元220‧‧‧第二有機發光二極體單元230‧‧‧第一透光面240‧‧‧第二透光面250‧‧‧顯示部260‧‧‧延伸部300‧‧‧可撓性電路板310‧‧‧表面400‧‧‧光感測器410‧‧‧感測面500‧‧‧生理資訊運算模組600‧‧‧顯示框L1‧‧‧第一光線L2‧‧‧第二光線O‧‧‧開口S‧‧‧穿戴空間
