A LCD display includes a light source section, a LCD panel including a plurality of pixels each having sub-pixels of R, G, B, and Z, and a display control section including an output signal generation section. The display control section performs a display drive on the sub-pixels with use of the respective output video signals, and performs a lighting drive on the light source section with use of the lighting signal. The output signal generation section generates output video signals corresponding to the respective four colors, based on the input video signals, and generates a lighting signal of the light source section, based on the input video signals, to perform a predetermined dimming processing, based on both the input video signals and the generated lighting signal, and finally generates the output video signals through performing a predetermined color conversion processing, based on a resultant video signal from the dimming processing.

Provided are: a paste composition which is capable of keeping a desired function for a backside electrode of a solar cell and strengthening the bond between an aluminum electrode layer and a p type silicon semiconductor substrate even if glass frit as a substance giving a bad effect on the environment is not incorporated into the composition or the content of glass frit as a substance giving a bad effect on the environment therein is decreased; and a solar cell element provided with an electrode formed by use of the composition. The paste composition is a paste composition for forming an aluminum electrode layer (8) over a p type silicon semiconductor substrate (1), comprising aluminum powder, an organic vehicle, and a metal alkoxide. The solar cell element provided with the aluminum electrode layer (8) formed by applying the paste composition having the above-mentioned characteristic to the p type silicon semiconductor substrate (1) and then firing the resultant.
