- Processing to reduce the brightness is expressed by the following formula (1).
- LVdwn-out represents the level of luminance when the luminance is reduced and output. Further, LVdwn-in represents a luminance input value that should be reduced in luminance.
- the control unit 1 proceeds to the next step 109 when the luminance is reduced without inverting the luminance.

- LVrvs-in represents an input value of luminance that should be inverted.
- control unit 1 When the luminance of the pixel is inverted, the control unit 1 then reduces the luminance of the pixel using the above equation (1) (step 108).
- control unit 1 proceeds to the next step 109.
- step 105 when the pixel is not a pixel in an area on the screen where the same image is fixedly displayed (NO in step 105), the control unit 1 inverts the luminance or reduces the luminance.
- the process proceeds to the next step 109 without executing the process. For example, it is determined that the pixel corresponding to the position where the diagnostic image 11 is displayed is not within the region, and the process of inverting the brightness or reducing the brightness is not executed.
- step 109 the control unit 1 counts the deterioration coefficient for each pixel.
- the deterioration coefficient is a value that takes a higher value as the luminance is higher.
- the control unit 1 displays the first part in the region displayed with relatively high luminance in the first mode and displayed with relatively low luminance in the second mode.
- the first deterioration degree is measured.
- the control unit 1 displays the second degree of deterioration of the second portion in the region that is displayed with relatively low luminance in the first mode and displayed with relatively high luminance in the second mode. And measure.

In the description here, it is assumed that the first mode is set at the first activation. In step 202, when the mode is set to the first mode, the control unit 1 ends the process.
- the control unit 1 calculates the difference between the first deterioration degree and the second deterioration degree, and the absolute value of this difference sets the threshold Th. It is determined whether or not it exceeds (step 203).
