Description

Display apparatus Cross Reference to Related Applications The present disclosure claims priority from japanese patent application No. 2024-194329 filed on 11/6 of 2024 and japanese patent application No. 2025-116645 filed on 7/10 of 2025, the entire disclosures of which are incorporated herein by reference. Technical Field The present disclosure relates generally to a display device. Background Display devices mounted on vehicles, notebook computers, and the like need to be waterproof. For example, even when drinking water is sprinkled onto a display device mounted in a vehicle, the display device is not expected to be damaged by the drinking water. One known method involves providing a display device with a waterproof sheet. For example, japanese patent No. 5222987 discloses a display device including a display panel, a frame member, and a waterproof sheet. The display panel may be a liquid crystal display panel, an organic-Electroluminescence (EL) display panel, or the like. The frame member supports an outer peripheral portion of a display surface of the display panel. The waterproof sheet is attached to one side of the display panel connected to the circuit board and extends along a surface of the frame member facing the display panel between the display panel and the frame member. In japanese patent No. 5222987, when moisture enters the frame member through a gap between the display panel and the frame member, the moisture accumulates between the waterproof sheet and the frame member. This prevents the circuit board from corroding due to moisture. However, this requires a frame member supporting an outer peripheral portion of the display surface of the display panel, and thus the features of japanese patent No. 5222987 cannot be applied to a display device that does not include the frame member. Further, as moisture accumulates between the waterproof sheet and the frame member, the waterproof performance of the display device disclosed in japanese patent No. 5222987 is insufficient. In view of the above, an object of the present disclosure is to provide a display device having high waterproof performance.
