Summary:To improve display quality even in a state where a display panel is physically deviated from an illumination device.SOLUTION: A display device comprises: an illumination device; a display panel; a memory; and a correction circuit. The illumination device has a light-emission area which has light-emission zones partitioned corresponding to light sources. The display panel faces the light-emission area, and has a display area having pixels arranged. The display area has display zones partitioned to face the light-emission zones. In the memory, data of a pixel matrix which is composed of pixels associated with the display zone is stored, and positional data and positional deviation data of a pixel which does not face the light-emission area are stored when positional deviation is generated between the light-emission area and the display area. The correction circuit determines whether or not the positional data of the pixel is stored in the memory, and when the positional data is stored, associates a new pixel matrix with each of the display zones on the basis of the positional deviation data.SELECTED DRAWING: Figure 5 【課題】表示パネルが照明装置に対して物理的にずれた状態であっても表示品位を向上させる。【解決手段】表示装置は、照明装置と、表示パネルと、メモリと、補正回路と、を備える。照明装置装置は、光源に対応付けられて区分された出光区域を有する出光領域を有する。表示パネルは、出光領域と対向し、画素が配された表示領域を有する。表示領域は、出光区域に対向するように区分された表示区域を有する。メモリには、表示区域にひも付けられた画素からなる画素行列のデータが保存されており、出光領域と表示領域との間に位置ずれが生じていた場合に出光領域とは対向していない画素の位置データと位置ずれデータとが保存される。補正回路は、画素の位置データがメモリに保存されているか否かを判断し、保存されている場合は、位置ずれデータに基づいて新たな画素行列を表示区域のそれぞれにひも付ける。【選択図】図５
