摘要： A light source module of the present invention includes: a plurality of light guide bodies (21) provided in parallel to one another with respect to a longitudinal direction; light sources (30) each causing light to enter each of the plurality of light guide bodies from at least one end surface in a longitudinal direction of the each of the light guide bodies (21); a light source wiring boards (32) having the light sources (30) and lines provided thereon, the lines being for electrically connecting the light sources (30) and including positive potential lines and negative potential lines; and an LED driver circuit (40) for performing a drive for turning on the light sources (30). Each of the light sources (30) provided to the light guide bodies (21) are independently driven by the LED driver circuit (40) so that each of the light sources (30) is independently turned on. Among lines provided on the light source wiring board (32) connected to the light sources 30, at least two high potential anode lines (30a) is arranged to be a common line. This makes it possible to provide a light source module whose thickness can be reduced by reduction of a wiring area, and an electronic device including the light source module, in a case where a side edge light guide plate is divided into a plurality of blocks.

摘要： An object of the present invention is to obtain a display device having excellent display quality by appropriately modifying the chromaticity of images. In this display device, a correction processing part (CPU 30) determines a first chromaticity change amount stored in memory (31) on the basis of a first cumulative usage amount, which is the cumulative usage amount of an LED (17) up to a present time, the cumulative value having been measured by a counter (32), and the correction processing part also determines a second chromaticity change amount stored in the memory (31) on the basis of a second cumulative usage amount, which is the cumulative usage amount of the LED (17) up to a time when the chromaticity of a pixel is adjusted by a chromaticity adjusting part (CPU 30), the cumulative value having been measured by the counter (32). Then, by subtracting the second chromaticity change amount from the first chromaticity change amount, the correction processing part obtains the value to which the chromaticity is to be modified, and modifies an image signal on the basis of the value to which the chromaticity is to be modified.
