The present disclosure provides an optical imaging lens assembly and an electronic device. The optical imaging lens assembly includes, sequentially from an object side to an image side along an optical axis, a window member; a first lens having a positive refractive power, and an object-side surface of the first lens being a convex surface; a second lens having a negative refractive power; and at least one subsequent lens having a refractive power, wherein an entrance pupil diameter EPD of the optical imaging lens assembly and half of an effective aperture DTg of the window member at an object-side surface thereof satisfy: EPD/DTg&#x3e;1.6, which makes the optical imaging lens assembly have the characteristics of high resolution and miniaturization. When the optical imaging lens assembly is installed on an electronic device, it can minimize the impact on the full-screen display.
