Display device

摘要

An illuminating device includes: a light source; a light guide plate which converts light emitted from the light source into a surface light ray and emits the surface light ray through a front surface of the light guide plate; and an optical sheet which changes a propagation direction of the surface light ray emitted from the light guide plate. The light source is arranged in opposition to one end surface of the light guide plate. A polarization state converting structure to convert a polarization state of the light propagating through the light guide plate is provided in a rear surface of the light guide plate. The polarization state converting structure contains an inclination plane having a ridge line extending in a direction perpendicular to the extension direction of the one end surface.

1. A display device comprising:
a display area in which a plurality of pixels are arrayed and a peripheral area outside of the display area; a plurality of scanning signal lines and a plurality of video signal lines, each of the plurality of pixels is configured by an area surrounded by the two adjacent scanning signal lines and the two adjacent video signal lines; lead lines formed in the peripheral area and electrically connect the video signal lines or the scanning signal lines with a driver circuit or a terminal portion that receives an output from the driver circuit; an insulating film formed on the lead lines and covering the lead lines; and a conductive film formed on the insulating film, wherein the driver circuit or the terminal portion is arranged in the peripheral area next to the display area in a first direction, wherein the lead lines include first lead lines and second lead lines, wherein the first lead lines overlap with the conductive film through the insulating film, and the second lead lines do not overlap with the conductive film, wherein wiring resistances of the first lead lines between the driver circuit or the terminal portion and the scanning signal lines or the video signal lines are smaller than wiring resistances of the second lead lines between the driver circuit or the terminal portion and the scanning signal lines or the video signal lines, wherein the plurality of the first lead lines are connected to the video signal lines or the scanning lines in the peripheral area next to the display area in a second direction perpendicular to the first direction, wherein the plurality of the second lead lines are connected to the video signal lines or the scanning signal lines in the peripheral area next to the display area in a third direction opposite to the second direction, and wherein the conductive film covers the first lead lines and is provided between the adjacent two first lead lines.
