There is provided a display device including a display unit having pixels, each of which includes a luminescence element for individually emitting light depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a picture signal, scan lines which supply a selection signal for selecting the pixels to emit light to the pixels in a predetermined scanning cycle, and data lines which supply the picture signal to the pixels, the pixels, the scan lines, and the data lines arranged in a matrix pattern, the display device including: a luminescence amount detector for inputting a picture signal with a linear characteristic to detect a luminescence amount from the picture signal; a luminescence time calculator for calculating a luminescence time for the luminescence element based on the luminescence amount detected by the luminescence amount detector; a luminescence time recorder for recording the calculated luminescence time; a luminance acquirer for acquiring luminance information of the luminescence element by use of the luminescence time recorded in the luminescence time recorder; a coefficient calculator for calculating a coefficient by which the picture signal is multiplied, based on the luminance information acquired by the luminance acquirer; and a coefficient multiplier for multiplying the picture signal by the coefficient calculated by the coefficient calculator.

A bolt supply device includes a slide plate inclined to a vertical direction; and a groove portion formed in the slide plate and having a width that allows passing of a screw portion of a bolt and prevents passing of a flange portion of the bolt. The groove portion includes a first groove configured such that an angle formed between a line extending in an up-down direction along the slide plate and the first groove is a first angle; and a second groove connected to a lower end of the first groove and configured such that an angle formed between the line extending in the up-down direction along the slide plate and the second groove is a second angle smaller than the first angle. The bolt take-out portion is set in the groove portion at a lower end or below the lower end of the second groove.

According to a compressor and a refrigeration cycle device using same of the present invention, a refrigerant and refrigeration oil 103 are sealed in an container 101, the refrigerant is a hydrofluoroolefin having double bond of carbon in its composition or a mixture of hydrofluoroolefin as a base component and hydrofluorocarbon having no double bond, and at least one of benzotriazole, dialkyl dithiophosphoric acid zinc, dialkyl selenium, metal phenate, and organic nitrogen compound is included in the refrigeration oil 103, and it is an object to suppress the decomposition and polymerization of refrigeration oil and a refrigerant, and to secure reliability of the compressor and the refrigeration cycle device.

A display panel and a demultiplexer circuit are provided. The demultiplexer circuit includes a first to a Pth switch units. The first to the Pth switch units are coupled to a first to a Pth data lines of a display panel respectively and collectively receive a data voltage and turn on sequentially in sequence to provide the data voltage to corresponding data lines. A period of the first to the Pth switch units provide the data voltage to the first to the P data lines sequentially which is defined to a data transmission period. When the switch unit is turned on, N transistors are turned on simultaneously according to a plurality of control signals. When the switch unit is turned off, at least one of the N transistors is turned off according to a corresponding control signal.
