| 摘要 | A display device has an NTSC ratio of higher than or equal to 80% and a contrast ratio of higher than or equal to 500 and includes a display portion. In the display portion, pixels are provided at a resolution of greater than or equal to 80 ppi, and the pixels each includes a light-emitting module capable of emitting light with a spectral line half-width of less than or equal to 60 nm in a response time of shorter than or equal to 100 μs. Further, transient characteristics of the emission intensity of the light-emitting module have a projecting portion higher than other portions in a portion rising in response to an input signal. | ||

| 主权项 | 1. A display device comprising: a display portion in which pixels are provided at a resolution of greater than or equal to 80 ppi, the pixels each comprising a light-emitting module capable of emitting light with a spectral line half-width of less than or equal to 60 nm in a response time of shorter than or equal to 100 μs, wherein the display device has an NTSC ratio of higher than or equal to 80% and a contrast ratio of higher than or equal to 500, and wherein a transient characteristic of emission intensity of the light-emitting module has a projecting portion in a portion rising in response to an input signal, the projecting portion having a higher emission intensity than other portions of the transient characteristic. | ||
