The present invention aims to provide an optical canvas frame that can provide a point light source effect and a surface light source effect at the same time, thereby providing various artistic inspirations and atmospheres to a user by optical effects. According to the present invention, the optical canvas frame is characterized by comprising: a canvas; a base arranged so that a surface facing the canvas is placed apart; a spread plate located between the canvas and the base; a light source module and an optical fiber located between the base and the spread plate; and a light output apparatus which outputs the light with the optical fiber. The optical canvas frame is characterized by providing the light source module, which irradiates light to the spread plate, and the optical fiber, which passes through the spread plate and the canvas to be exposed to the outside of the canvas, and which is activated by the output light of the light output apparatus to provide the light to the outside of the canvas.
