An electronic device is disclosed and includes an optical sensor module, a window, a first shield-printed layer, and a second shield-printed layer. The optical sensor module includes a first optical sensor and a second optical sensor. The window covers the optical sensor module. The first shield-printed layer is printed in a first region for transmitting a sensor light from the first optical sensor on a lower surface of the window facing the optical sensor module. The second shield-printed layer is printed in a second region for transmitting a sensor light from the second optical sensor on the lower surface of the window. The first and second shield-printed layers are printed using a same coloring material.
