Abstract

Abstract PURPOSE:To form a high quality image by controlling a linear light source so that blocks in the linear light source corresponding to respective blocks in a microshutter array are turned on synchronously with the opening/closing operation of a microshutter in each block of the microshutter array. CONSTITUTION:The microshutter array 100 consisting of plural microshutters is a liquid crystal shutter array divided into (n) blocks and gate electrodes G1-Gn are connected to the gates of thin film transistors in respective blocks. An LED array 101 to be a light source is also divided into independent blocks corresponding to respective blocks in the shutter array 100 at the rate of 1 to 1, switching elements 401-1-401-n are formed in respective blocks and selecting signals B1-Bn for respective blocks are supposed to respective control electrodes in the switching elements 401-1-401-n. Respective LED blocks have independent power sources 410-1-410-n so as to be driven in accordance with the signals B1-Bn. Thus, a high quality image can be always formed.
