Abstract: A wearable display device (10), including a display panel (101) and a slit grating (102) disposed on a light-emitting side of the display panel (101). Rays emitted by sub-pixels (101111) in the display panel (101) may be exited from slits (102a) in the slit grating (102). In addition, as the rays emitted by the sub-pixels (101111) may be intersected after passing through the slits (102a), the wearable display device (10) may include at least two imaging faces (K, C). In this way, focus points of two eyes of a user are a same point on the at least two imaging faces (K, C) when the two eyes of the user focus on one of the at least two imaging faces (K, C) by a lens focusing function of the two eyes, so as to avoid visual fatigue of the user. Thus, the wearable display device (10) has a better display effect.
