Provided are an anti-reflective glass screen-chalkboard capable of obtaining a clear image even at a very short distance by securing a wide view angle with reduced right and left blind ranges of an existing anti-reflective glass screen; and a manufacturing method thereof. To achieve this, the present invention bonds an expansion film having a projection screen and the outline of an opaque plate glass, airtightly by an airtight bonding layer; and forms a nanobead layer inside of the outline of the opaque plate glass and the expansion film in which the airtight bonding layer is not yet formed, therefore, a uniform bright screen can be created without vertical and horizontal variations even at a rapid incidence angle. |
