An image including reduced speckle noise is formed.
Thus, an oscillation spectrum of the laser light source is widened and speckle noise is reduced.
It is possible to reduce the speckle noise with simple configuration in a 2-dimensional image display device.
The laser diode (10) is driven by an up-ramp signal that reduces electronic processing and at a frequency that reduces speckle noise.
According to the arrangement, it is possible to effectively reduce speckle noise existing on an image projected onto a screen (11).
