Both Panasonic LX7 and Nikon L100 have 10.0 MP resolution sensors but Panasonic LX7's sensor is 1/1.7-inch (7.44 x 5.58 mm ) and Nikon L100's sensor is 1/2.3-inch (6.08 x 4.56 mm ).
Since Panasonic LX7's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon L100.
Below you can see the LX7 and L100 sensor size comparison.

As seen above, Panasonic LX7 has a 1.5x Larger sensor area than Nikon L100. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic LX7
or the
Nikon L100 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.7-inch versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
