Description of the Related Art In an electrostatic digitizer or the like, electrodes are arranged in a matrix in an X-axis direction and a Y-axis direction on a glass plate of a display screen, and a delay pulse is sequentially applied to the electrodes in each axis direction. The pulse at the position touched by the stylus pen is detected, this signal is converted into a required digital signal, processed by an arithmetic circuit, converted into coordinate data corresponding to a digital value, and output. In this case, for example, in a display of a stripe type pixel, when the pitch of the pixel of the display and the pitch of the electrode do not match, interference fringes are generated. Therefore, as shown in FIG.
The pitch of 1, Y2, ... is the same as the pitch of the display pixels, and the position is adjusted so that the electrodes in the Y-axis direction do not overlap the pixels (the figure shows the electrodes being between green and blue) ), The adjustment requires precision, and if there is a misalignment, the same color part of each pixel will be blocked by the electrode,
For example, when the overlapping electrodes are red, there is also a problem that the amount of red light decreases and the color becomes cyanish.
