Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of U.S. provisional application Ser. No. 63/458,900, filed on Apr. 12, 2023. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The application relates to a display device, and in particular, to a head mounted display device and a light-shielding face mask thereof. Description of Related Art The most common type of display device currently used for virtual reality is a head mounted display device. The head mounted display device requires appropriate a face mask to block light to prevent light leakage from affecting visual performance. In order to meet the head sizes of different users and the users' needs for wearing glasses, the light-shielding face mask needs to be designed in multiple sizes. SUMMARY The application provides ahead mounted display device whose light-shielding face mask itself can automatically adapt to the size of the user's head to cover the user's eyes. The application provides a light-shielding face mask adapted for a head-mounted display device, which can automatically adapt to the size of the user's head to cover the user's eyes.
