Claims (1)

[Claims for Utility Model Registration] 1. A line information signal that simultaneously outputs line information of a set width in the horizontal or vertical direction on a display screen during the same time based on the display information, and display information of the line information signal. a display control unit that outputs a line scanning control signal that controls the scanning order of lines for the display control unit; a light source unit that controls light emission in response to a line information signal or a line scanning control signal output from the display control unit; a display section in which a plurality of light-transmitting optical waveguides that are configured to confine light emitted from the section are arranged in parallel on the same plane and in the same direction at set value intervals; and a display section located so as to intersect the display section. a scan control section that receives a line scan control signal or a line information signal output from the display control section and performs scan control of the display section; 1. An image display device comprising: a refractive index changing unit that changes the refractive index of a line corresponding to a line information signal. 2. The display control section includes a line information storage circuit that stores line information of a set width in the horizontal or vertical direction on the display surface based on the display information and outputs a line information signal; The image display device according to claim 1, characterized in that the image display device comprises a line scanning circuit that controls scanning of outputted line information and outputs a line scanning control signal. 3 The refractive index changing section changes the refractive index of the optical waveguide due to an electro-optic effect, a thermo-optic effect, an acousto-optic effect, or an external mechanical force, and leaks the light source to the outside from a predetermined position of the display section to emit light. An image display device according to claims 1 and 2 of the utility model registration claims.
