Abstract
The present invention aims to provide a liquid crystal display panel having a structure in which a plurality of gate electrodes are arranged on a continuous semiconductor layer and still capable of suppressing increase of a parasitic capacitance between a source region and a drain region. The liquid crystal display panel of the invention includes a thin film transistor. The thin film transistor includes: a base insulating film; a semiconductor layer extending linearly at least from a first portion to a second portion; a source electrode; a drain electrode; and gate electrodes, respectively, to cover the semiconductor layer with a gate insulating film therebetween. A light shielding film is arranged to cover each projection region corresponding to projection of the gate electrode. The light shielding film is arranged in the form of a plurality of light shielding film elements. The light shielding film elements each cover one or more projection regions.
