Abstract: PROBLEM TO BE SOLVED: To provide a surface light source device, capable of efficiently the light from a point light source into a surface light source and and superior in luminance and uniformity, and to provide a light guide plate capable of forming a bright and easily visible transmission or reflection type liquid crystal display device. SOLUTION: This light guide plate is produced by partially connecting a surface light guide plate 11, which converts the incident light from a linear light source into a surface light source and a linear light guide plate 12, which converts the incident light from a point light source 15 into linear light source. The surface light source device 2 is produced, by disposing a point light source for the linear light guide of the light guide plate. The liquid crystal display device includes at least the surface light source device and a liquid crystal cell. By this method, the linear light source can be easily positioned with high accuracy with respect to the entrance side of the surface light guide plate and in a superior state of the incident efficiency of light.  Another holding mechanism of the linear light guide plate can be dispensed with, to decrease the number of parts, and therefore, a compact surface light source device or a liquid crystal display device with low consumption of electric power can be obtained with high production efficiency.

The resistors 2 and 3 are connected to a flow sensing circuit 5 which measures the flow rate of air on the basis of changes in the resistance values of the resistors, while the electrodes 4a and 4b are connected to a power source unit 6. When the electrodes 4a and 4b are short-circuited by extraneous matters 7 such as carbon which stick to and is deposited on the surface of the resistor 2, a current flows between the electrodes 4a and 4b from the power source unit 6 through the intermediary of the extraneous matters 7. The temperature of the extraneous matters 7 is increased directly and thus these matters are burnt away.
