Displacement Map doesnt work well

I'm trying to make a glitch effect by using the Displacement Map effect
but I'm getting something else.

You don't need to do this on an adjustment layer. In fact, it's causing problems.
You need two things for the distortion map: the layer you want to distort, to which you apply the effect, and a layer that provides the luminance information to drive the amount of distortion. You tell the efcect to look at this layer in the effect settings.

Play around with it -- you'll figure it out.

Based on the description of what you want, you will need to create a separate texture for the displacement. For instance, you could:

-create a new solid with a fractal noise effect on it
-Set the noise type to "Block" and increase the contrast
-Precompose the solid (Move all attributes")
-Choose the precomp as your displacement map layer
-Where it says "Red" and "Green", set both of those to "Luminance".

If you animate the evolution of your fractal noise, you should now see it affecting the text.

And actually, the featured tutorial on the homepage today covers this exact effect:
