Wide lateral angle frontlight for use with reflective displays

A device, comprising:

• a top end and a bottom end opposite the top end;
• a left side and a right side opposite the left side;
• a first light source and a second light source positioned proximate to the top end of the device;
• a first light guide including first refractive features and a second light guide including second refractive features, the first light guide and the second light guide extending linearly from the top end to the bottom end of the device, the first light guide configured to receive first light from the first light source, and the second light guide configured to receive second light from the second light source, the first light guide at least partially overlapping the second light guide, wherein the first light guide is positioned at a first angle with respect to a first axis that spans from the top end to the bottom end, and wherein the second light guide is positioned at a second angle with respect to the first axis;
• and
• a reflective display configured to cause presentation of content using the first light and the second light.
