In an embodiment, a terminal device includes a display unit having a display screen, and a light sensing unit located below the display unit and configured to sense incident light transmitted through the display screen. The display unit includes a transparent electrode, an opaque electrode, and an organic layer sandwiched between the two electrodes. The organic layer spontaneously emits light when a voltage difference is applied between the two electrodes. The second electrode has a semi-transparent area disposed corresponding to the light sensing unit and a remaining area which is an area of the second electrode except for the semi-transparent area. Also, an image capturing method is provided.
