A keyboard device is located in an accommodating space of a housing having first openings and a second opening. The keyboard device includes a flexible body and a transparent liquid. The flexible body is located in the accommodating space, and includes a main body, first pressing portions, patterns, and a second pressing portion. The first pressing portions are respectively located in the first openings. The patterns are located on the main body or the first pressing portions and are respectively exposed through the first openings. The second pressing portion is located in the second opening. The main body, and the first and second pressing portions have an enclosure space therein. The transparent liquid is located in the enclosure space. When the second pressing portion is pressed, the first pressing portions expand to protrude from the first openings, such that the patterns are enlarged. |

1. A keyboard device located in an accommodating space of a housing, wherein the housing has a plurality of first openings and a second opening, and the first and second openings are communicated with the accommodating space, and the keyboard device comprises:
a flexible body located in the accommodating space and comprising:
a main body;a plurality of first pressing portions protruding from the main body and respectively located in the first openings;a plurality of patterns located on a surface of the main body or surfaces of the first pressing portions, wherein the patterns are respectively exposed through the first openings; anda second pressing portion protruding from the main body and located in the second opening, wherein the main body, and the first and second pressing portions have an enclosure space therein, such that the main body, and the first and second pressing portions are communicated with each other; the area and the height of the second pressing portion are respectively greater than the area and the height of each of the first pressing portions; and a transparent liquid located in the enclosure space, wherein when the second pressing portion is pressed, the first pressing portions expand to protrude from the first openings due to the transparent liquid flowing into the first pressing portions, such that the patterns are enlarged; the viscosity of the transparent liquid is in a range from 1500 to 50000 CPS, such that when the second pressing portion is released, the patterns remain enlarged for a period of time. |
