A liquid crystal display (LCD) device and an organic light-emitting diode (OLED) display device are disclosed. The LCD device includes a base substrate, a display module, and a liquid crystal lens layer. The display module includes a fingerprint recognition sensor. The OLED display device includes a base substrate, a fingerprint recognition sensor, a two-layered liquid crystal lens layer, and an OLED display. The liquid crystal lens layer is configured to be switchable between a non-lens state and a lens state. By adopting liquid crystal lenses with holes, utilization of reflected light reflected by a fingerprint can be improved and imaging quality can be optimized.
